How will China's mines develop in the future?

After decades of crude mining-style development, China's mines have now shown polarized characteristics: large-scale intelligent and micro-workshop-style, and recyclable resource utilization will be the main development direction, that is, future mines will gradually surpass: large-scale, intelligent, green, and recyclable development, small and medium-sized mines that are not up to standard will be gradually closed!

Working characteristics of coal mining machinery and equipment

Most of China's coal mines are underground mining, and the working environment is very complex and harsh, so the performance and technical requirements of machinery and equipment are very high.First of all, coal mining machinery and equipment must have the function of continuous operation. Coal mining work is sometimes uninterrupted, so the machinery and equipment can also meet the requirements of running time.Secondly, the mining environment is harsh, and a large amount of dust may be generated, which will damage the performance of machinery and equipment and affect its normal operation.Finally, friction, excessive load and vibration will occur during the operation of machinery and equipment. In addition, the underground mining space is small. In order to ensure the effective transportation of coal, the size design requirements of machinery and equipment are also very high.Because machinery and equipment operate in harsh environments for a long time, failures are inevitable, and once a failure occurs, it is very difficult to repair it. This requires a good job of usual equipment maintenance and overhaul, and improve the overall level of fault diagnosis of machinery and equipment.

Causes of mechanical and electrical equipment failures

The failure of the machine is mainly due to the inability of certain parts in the machine to provide specific functions, causing problems in the operation of the equipment.During the service cycle of the equipment, the longer the equipment is used, the more likely it is to wear and tear, and the equipment will be overloaded multiple times during long-term operation.The most common causes of mechanical and electrical equipment failure include: (1) Wear and tear of parts.The degree of wear of parts is proportional to the time of electromechanical operation. The longer the running time, the greater the degree of wear.When the equipment is running to a certain point in time, the parts will age, and the parts will no longer be able to support their own functions, which will eventually cause mechanical and electrical equipment failure.(2) Failure and maintenance.Failure or failure to follow appropriate procedures will cause the greatest damage to the equipment. For example, sudden shutdown of the equipment may cause voltage or current mutations, which will cause damage to some fragile components; unreasonable maintenance will further damage the equipment, including untimely maintenance, insufficient maintenance and inappropriate maintenance methods.(3) Overload operation.Some enterprises use mechanical and electrical equipment for too long due to efficiency or other reasons, and overloaded work reduces the service life and increases the incidence of equipment failures during the service cycle [1].
