复杂区域受采动动压影响全煤巷道锚网支护技术

Complex Areas Affected by Mining Dynamic Pressure Effect Full Roadway Bolting with Mesh Coal Technology Research and Practice

为近距离煤层群开采,改善矿井复杂地质与工程条件以及工作面的衔接紧张造成煤层压茬关系紧张,开滦范各庄矿业分公司在3623风道开展复杂区域受采动动压影响全煤巷道锚网支护技术研究与实践,优化支护参数,提升支护强度,为此类巷道支护提供有力技术支撑。结果表明受多次采动影响而变形严重的巷道,重新满足了运输、行人的需要,实现了安全高效矿井建设,取得了显著的经济和安全效益。

In order to conduct close seam group and improve mine complex geological and engineering conditions and the tension caused by the convergence of face stubble seam pressure,Kailuan Mining Fangezhuang Mine carried out complex region in 3623 working face affected by mining dynamic pressure full roadway bolting wire technology research and practice,optimized supporting parameters to enhance the strength of support for this type of roadway to provide strong technical support. So that by repeatedly deformed severely affected by mining roadway,re-met the transportation needs of pedestrians to achieve a safe and efficient mine construction. The technology has achieved remarkable economic and security benefits.
