The theory of essence security believes that due to the impact of various environments, the degree of freedom of people will increase, and security and reliability will deteriorate. Therefore, in order to ensure safety, science and technology that can ensure the safety of personal and property even if there are artificial errors, so that it can achieve "essential security".

　　Mining improves steel wire rope more in the throat of the mine. During the operation of the device, repeated loading and release will cause the irreversible mechanical performance loss of the wire rope. For a long time, it lacks more reliable prevention methods. Coal mines are often trapped in "hidden dangers, waste, inefficient" because of improving steel wire ropes. The three major contradictions are in the dilemma. Traditional artificial inspections are not reliable, and it is difficult to effectively find hidden dangers on the wire rope; regular changes to the rope cannot ensure safety, and cause huge waste of the wire rope; overdoing the production time of the steel wire rope, resulting in the air consumption of the equipment and low efficiency.

　　1 Existing problem

　　Zheng Coal Group Luogou Coal Mine had an improvement of the steel wire rope three years ago, causing the Dou Dou to fall into the well, which affects the production of up to 116 hours. After that, the 6 large main mines of Zhengmei Group Corporation later investigated and analyzed one by one one by one: All 4 multi -ropes friction -type rackets are required to use the period of 2 years. Defects; 5 single ropes wrapped rope steel wire ropes averaged 2.7 years on average. The use loss of wire rope is more serious. The dangerous situation of critical broken ropes and even facts of facts in normal use periods.

　　Based on the results of this survey, Zhengmei Group decided to adopt the technical means of effective non -destructive testing and scientific assessment of the use of steel ropes, so that the mines improved the safety of transportation safety to get both the symptoms.

　　2 Adopt advanced detection technology to control hidden dangers of steel wire ropes

　　The coal mines of Zhengmei Group were first equipped with TCK.W portable steel wire rope without damaged probe. This instrument adopts weak magnetic detection technology, which can quantitatively detect various damage such as the inner and outer wire, wear, rust, fatigue, etc. of the wire rope, and accurately evaluate the remaining load capacity and service life of the wire rope. The instrument is combined with a number of advanced technologies, exquisite structure, lightness, good through nature, simple and convenient operation, safe and reliable use, anti -water and anti -interference of the whole machine, suitable for more harsh working conditions.

　　Adopting advanced testing technology to replace the backward method of manual inspection, achieved immediate security effectiveness and economic benefits. Zhengmei Group's original 1 imported steel wire rope, which promised 4 years, has less than 0.5 years. When testing it, it is clearly detected by 6 serious damage, and the maximum damage value reaches 10.6%. use. Without this test, the rope may cause severe crane accidents at any time. Because it has always been difficult to accurately evaluate the actual technical status of the wire rope, the foreign suppliers of the wire rope seriously suspect the basis for quality claims in warranty. The TCK.W scientific instrument and TCK.W data report presented by the miners made the foreign supplier of the wire rope finally confirmed the test results and compensated Zhengmeo Character to the economic loss of 920,000 yuan.

　　3 Create a new model of steel wire rope safety supervision

　　Through further exploration and research on the safety supervision method of steel wire rope, Zheng Coal Group realized that although the portable probe provides a certain technical guarantee for the safe operation of the wire rope, due to the great impact of the wire rope load, the high -yield coal mines are continuously run 24h, and the high -yield coal mines are continuously operated by 24h. There are many human factors such as the operation of the instrument operation and the production time of the discontinuation of production. There is still a significant gap between the actual safety status of the mining wire rope and the essential safety requirements. A dynamic and continuous steel wire rope must be used online to automatically detect the scheme to finally achieve scientific supervision and reliable prevention and control of the mining wire rope.

　　In 2008, TCK.W steel wire rope weak magnetic detection technology successfully merged modern high -tech results such as Ethernet Communications, Microelectronics Integration, and two -dimensional model analysis. It can achieve remote monitoring for the wire rope in major production and public facilities. Zhengmei Group Zhaojiazhai Mine immediately organized technological backbones and TCK.W Company to conduct new technological research, developed a wire rope online real -time automatic detection system. In the magnetic field environment below 200mt, the mines were detected in all -weather to increase the inside and outside of the wire rope in various parts Damage, monitoring process without magnetic pollution. The exit gap on the surface of the sensor and the wire rope reaches 50mm, and the uncertainty of the loss rate of the cross -sectional area of the steel wire rope caused by various damage is less than 0.5%.

　　The real -time automatic detection system of the wire rope is equipped with 5 technical units including mode combination detection, intelligent number adapter conversion, photoelectric test speed, self -control sound, light alarm, and multi -channel terminal main control. There are advanced functions such as all -weather automatic detection, automatic data integration, and automatic generating test report that do not require positions, which can realize "data sequence/damage curve/statistical chart multiple prefabrication", "background data operation", "automatic file construction", "system self -self -self Inspection "and" fault analysis "and other functions, and generate a processing plan, which requires close combination with the actual working ecology and safe operation of the mine improving machine, which can be detected online when the wire rope is detected normally. The system avoids the impact of people during the monitoring process to the maximum extent, and the scope of monitoring is further extended to parts that the inspectors cannot reach in the past, so as to achieve online real -time automatic monitoring of the full -cycle of the wire rope throughout the process. solution.

　　At present, the main auxiliary well of the Zhaojiazhai Mine of Zhengmei Group is engaged in running the online real -time automatic detection system of TCK.W — SC type 4 rope 8 -measuring steel wire rope. The corresponding online detection can be completed according to the itinerary. Once a severe damage signal is encountered during the testing process, the sound light warning will be automatically issued as soon as possible. At the same time, the computer system will also provide "enhanced maintenance", "stop review" or "immediately" or "immediately" or "immediately immediately" according to the detection data. Change the rope "equipment disposal plan. Ore

　　Some maintenance personnel had doubts about the data detected by the system in the early stage, but after detailed measurement, comparison and parameter profoundity, all technical indicators were fully verified on the scene. Reached.

　　4 Effect

　　In July 2009, the online detection system of the main auxiliary steel wire rope of Zhaojiazhai Mine was put into operation. After a period of on -site verification, the coal production was significantly improved. The cost of rope was controlled, and the detection of energy consumption was close to zero. The small investment of the enterprise has returned a large return and has become a new model of safety supervision for important use steel ropes.

The system has always been closely monitored by the operation of the wire rope, which fundamentally eliminates various hidden dangers to ensure the safety of raising machines.

　　(2) The production efficiency is significantly improved. According to the "Coal Mine Safety Regulations", it must be checked once a day to improve the wire rope and canned rope. At this request, Zhaojiazhai Mine consumes 1.5h per day for manual inspection of steel wire rope. After the real -time automatic monitoring system of steel wire rope is used, the steel wire rope detection is completed while normal production, so that the production and detection process will be combined into one. Wan T.

　　(3) Thoroughly eliminating air -rotating energy consumption caused by equipment detection Zhaojiazhai mine owner and sideline to increase the height of 446m and 465m, respectively, and the motor power is 2800 kW and 850kW, respectively. During the manual inspection, the rope speed was 0.3 to 0.5m/s, and the equipment was 235kW, and the artificial inspection required 350kW · H was required to complete the artificial inspection by 4 detection workers. At least 116,000 kw · h used for air -load energy for steel wire rope every year according to the effective working day of 330D each year. The use of the steel wire rope safety supervision system, the air -load energy consumption specially used for steel wire rope detection is almost zero, and the power saving benefits are nearly 100,000 yuan.

　　(4) Reasonable use of the surplus life of the wire rope Zhaojiazhai mine owner and the sideline racerometer in the past 2 years, the cost of each rope for 780,000 yuan, the maintenance of 250,000 yuan for maintenance The starting time reaches 3D, thereby accounting for 510,000 yuan in rope changes each year. After using the wire rope online real -time automatic detection system, the main and auxiliary wells to increase the steel wire rope because it can achieve the service period, and even extend the service life of one year. /3.
