摘要
针对河北金牛能源公司邢东煤矿-980 m采区第一联络巷失修严重的现实问题,对原支护方式做了理论分析,提出锚网索反底拱维修的技术方案,并在力学机理分析基础上,对邢东矿深井锚网索反底拱支护技术进行了理论分析和应用研究。最终实现成功支护,并取得良好的经济技术效果。
Aiming at practical problems of 980 Mining Area the first connecting tunnel disrepair in Xingdong Colliery,Hebei Jinniu Energy Co.,the authors made a theoretical analysis of the original support,put forward technical scheme of cable anchor and inverted arch maintenance,and made a theoretical analysis and application research on supporting technology of cable anchor and inverted arch in Xingdong Colliery,which achieved successful support and better economic technical benefits.
