摘要
针对煤层底板大巷受采煤工作面强采动影响的工程背景,以东曲矿28214采煤工作面为例,采用数值模拟法,得到强采动下采煤工作面矿压显现规律,提出了补强支护设计方案。经工业性试验,优化方案可靠,保证了巷道的稳定和安全服务。
Aiming at the engineering background that the main roadway of the coal seam floor is affected by the strong mining of the coal mining working face,taking the 28214 coal mining working face of Dongqu Mine as an example,using the numerical simulation method,the law of the rock pressure behavior of the coal mining working face under the strong mining is obtained,and the reinforcement support design scheme is proposed.The industrial test shows that the optimized scheme is reliable and ensures the stability and safety service of the roadway.
