巷道掘进支护技术存在的问题及改进措施分析

Analysis on the Existing Problems and Improvement Measures of Roadway Excavation and Support Technology

随着我国煤矿开采深度的不断增加,所需的巷道掘进量在随着增加,巷道支护难度也在随之增加,传统的巷道支护技术在很多方面已经表现出较大的不足,影响到巷道支护整体效果。本文将xx工程作为实际案例,剖析了巷道掘进支护技术存在的主要问题,并结合巷道所处地质实际情况,针对性提出了返修支护措施,取得了较好的现场支护效果。

With the continuous increase of coal mining depth in China,the amount of roadway excavation required is increasing,and the difficulty of roadway support is also increasing.The traditional roadway support technology has shown great deficiencies in many aspects,affecting the overall effect of roadway support.Taking XX project as an actual case,this paper analyzes the main problems existing in roadway excavation support technology,and puts forward repair support measures in combination with the actual geological situation of the roadway,which has achieved good on-site support effect.
