杏花煤矿西部采区运输大巷西二二区区段由于受地质条件影响和采动影响,再加之服务年限长等原因,部分地段出现严重变形,料石破损脱落,矿压显现明显,严重影响安全生产。为了及时合理地解决这一问题,通过现场观测和分析研究,找出了几方面原因,并运用锚索支护解决了巷道维修的关键技术问题,取得了较好的效果。
Due to the influence of geological conditions and mining and the long service life, serious deformation occurred in some sections in the section of the second and second districts of West Xinghua Coal Mine, western part of the mining area. The material rock was damaged and dropped off, and the mine pressure was obvious and severely affected Safe Production. In order to solve this problem in time and reasonably, several reasons are found out through on-the-spot observation and analysis and research. The key technical problems of roadway maintenance are solved by using anchor cable support, and good results are achieved.
