How to better realize rapid drivage has become the key problem facing the current coal mine production. Because the supporting efficiency of coal mine rapid excavation can not meet the corresponding requirements, it should be studied in this aspect to solve the problem of low coal mine production efficiency and better improve the economic benefits of coal mine enterprises.展开更多
文摘With the continuous acceleration of coal mine production speed, the workload of mine roadway drivage is also constantly improving. How to better realize rapid drivage has become the key problem facing the current coal mine production. Because the supporting efficiency of coal mine rapid excavation can not meet the corresponding requirements, it should be studied in this aspect to solve the problem of low coal mine production efficiency and better improve the economic benefits of coal mine enterprises.
