Wire rope intelligent monitoring technology is an important part of intelligent construction of mining industry (Bayangol Mine Application Case)
1. Bayangol coal mine elevator status overview
The main shaft of Bayangol mine is a 4-rope ground friction elevator, the lifting height of the main shaft is 595 meters, the lifting speed in the production process is 10.37 meters/s, the lifting cycle time is about 3 minutes, and the coal lifting volume in a cycle is 38 tons *2. The power of the lifting machine is 5000kW·h, and the lifting cycle is 20 times per hour, and the working days are 360 days per year.
2 TCK.W System application
1. Wire rope safety upgraded to highest level
Realize the replacement of manual detection with machine intelligence detection, complete the 24 hours X 365 days of wire rope life cycle safety monitoring, timely discovery of wire rope safety hazards, and completely eliminate broken rope accidents.
2. Complete big data intelligent monitoring at the same time of production, reducing cost and increasing efficiency.
2.1 According to the "coal mine safety regulations", the lifting wire rope must be checked once a day.
Ba Mine checks the wire rope once a day, the detection speed is 0.5m/s, and the time is 0.5h. The energy consumption of a test is 2500Kw, 10 lifting cycles are reduced, and the coal lifting amount is reduced to 760 tons. The annual inspection time of Ba Mine is about 180h, the inspection energy consumption is 900,000 kW·h, the lifting cycle is reduced by 3,600, and the coal lifting volume is reduced by 273,600 tons. According to the current price of 1760 yuan per ton of coal, the annual output value decreased by 481.5 million yuan.
2.3 After using the TCK.W system, Ba Mine can complete monitoring at the same time of production, reduce the annual shutdown time of 180 hours, can increase the raw coal production of 273,600 tons, and increase the output value of nearly 481.5 million yuan;
2.4 Save 900,000 kW·h of power consumption specially used for rope inspection, and save 369,000 yuan of electricity.
3 The effect of energy conservation and emission reduction is remarkable, helping to achieve the dual carbon goal.
The annual inspection energy consumption of Ba Mine is 900,000 kW·h, and the carbon dioxide emission is increased by 897,300 kg virtually. After using the TCK.W system, the annual detection energy consumption can be saved by 900,000 kW·h, and the carbon dioxide emissions can be reduced by 897,300 kg, providing a strong technical guarantee for the realization of the "double carbon" goal.
4 Save the cost of rope, to protect the environment to provide technical grasp.
The cost of a rope in Ba mine is 172.21 million yuan, the rope replacement cycle is 2 years, the average annual rope cost is 860,000 yuan, there may be a waste of wire rope. According to the coal mine safety regulations, after 2 years of wire rope use, if the wire rope is checked and the diameter is reduced and the degree of rust does not exceed the regulations, it can continue to be used for 1 year. We believe that the TCK.W intelligent monitoring system has the potential to extend the service life of the wire rope by at least one year and reduce the cost of rope by one-third under the premise of ensuring safety. The annual cost of rope can be reduced from 860,000 yuan to 570,000 yuan; The average cost of each rope is reduced by 860,000 yuan.
