浅述巷道支护技术在井下掘进中的应用研究

A Brief Discussion on the Application of Roadway Support Technology in Underground Excavation

随着我国煤炭需求的不断增加,煤炭的开采已经从露天开采发展到井下开采,并且随着煤炭资源的不断消耗,井下开采的量越来越大,这给煤炭开采工作带来了极大的挑战。在井下煤炭掘进过程中,巷道支护技术是常用的技术之一,其通过围岩支护、围岩加固以及多元支护等方式,有效的缓解了围岩变形的压力,提高了掘进速度,保证了掘进人员的安全。然而受一些因素的影响,该技术的应用现状不容乐观,因此本文以此为背景来对巷道支护技术在井下掘进中的应用展开研究,为井下煤炭的开采提供参考。

With the increasing demand for coal in our country,coal mining has developed from open pit mining to underground mining,and with the continuous consumption of coal resources,the amount of underground mining is increasing,which brings great challenges to coal mining.In the process of underground coal excavation,roadway support technology is one of the commonly used technologies.It effectively alleviates the pressure of surrounding rock deformation,improves the excavation speed,and ensures the safety of excavation personnel by means of surrounding rock support,surrounding rock reinforcement,and multiple support.However,due to the influence of some factors,the application status of this technology is not optimistic.Therefore,this paper takes this as the background to study the application of roadway support technology in underground excavation,hoping to provide reference for underground coal mining.
