With the rapid development of the industrialization process, all kinds of mines have basically realized mechanized or semi-mechanized mining operations, but what comes with it is the mutual support of corresponding machines and tools and large-scale industrial production. The main mining tool among them is the mining pick of comprehensive mechanized mining machine (such as shearer pick), its wear resistance and corresponding life directly affect production efficiency and production cost, traditional mining machine pick (such as Shearer pick) is a mining tool that is inlaid with a tungsten carbide cutter head into a stainless steel cutter body. It is mainly used for mining and excavation of roadways, tunnels, ground trenching and other projects; Machines, milling machines and other equipment are consumables. In particular, the shearer pick is one of the vulnerable parts in coal mining and tunneling machinery, and is the main tool for coal falling and crushing. The performance of the shearer pick directly affects the production capacity of the coal mining machine. , power consumption, working stability and service life of other related parts.                                                        

       The main failure modes of shearer picks are shedding of the cutter head, chipping and wear of the cutter head and cutter body. Under certain working conditions, the cutter often fails due to the breakage of the cutter body. Due to the continuous increase in the mining of coal and other mineral resources in recent years, the demand for mining picks has also increased accordingly. Therefore, major manufacturers have expanded production and improved product service life to meet the growing demand for mining picks (such as shearer picks). Improving the service life of mining picks can reduce the production cost of mining enterprises and reduce Small environmental pollution, in line with the development requirements of green low-carbon, energy saving and emission reduction, therefore, how to improve the service life of mining picks (such as shearer picks) has far-reaching significance for the development of coal and other mineral industries.
