煤矿井下采煤技术及问题分析

Analysis of Underground Coal Mining Technology and Problems

本论文深入探讨了煤矿井下采煤技术及其应用中存在的问题以及相应的对策。首先介绍了煤矿井下采煤的主要技术,包括水力采煤、机械化采煤、综合机械化采煤和爆破采煤。随后,详细分析了在采煤技术应用中存在的安全隐患、设备不先进、瓦斯爆炸风险和巷道支护与掘进等问题。为解决这些问题,提出了加强井下安全管理、优化采煤设备性能、加强井下瓦斯抽采和发展巷道快速掘进技术等对策。通过这些对策的实施,可以提高采煤效率、保障矿工安全,并促进煤炭工业的可持续发展。

This paper deeply discusses the problems existing in underground coal mining technology and its application and the corresponding countermeasures.Firstly,the main technologies of underground coal mining are introduced,including hydraulic coal mining,mechanized coal mining,comprehensive mechanized coal mining and blasting coal mining.Then,it analyzes in detail the problems in the application of coal mining technology,such as hidden danger,equipment is not advanced,gas explosion risk and roadway support and excavation.In order to solve these problems,countermeasures such as strengthening underground safety management,optimizing the performance of coal mining equipment,strengthening underground gas extraction and developing fast tunneling technology are put forward.The implementation of these measures can improve the efficiency of coal mining,ensure the safety of miners,and promote the sustainable development of coal industry.
