新陆煤矿复采安全技术与实践

Safety technology and practice of repeated mining in Xinlu Coal Mine

新陆煤矿可采煤层单一,开采深度大,煤炭资源几近枯竭。为了回收煤炭资源,延长矿井服务年限,利用浅部现有系统对11号煤层分阶段和分区段开采留设的阶段、区段煤柱进行复采,现场实践结果表明,复采技术是延长衰老矿井服务年限的有效途径,具有良好的经济效益和社会效益。

Xinlu coal mine can be mined coal seam is single, mining depth is large, coal resources almost exhausted. In order to recover coal resources and prolong the service life of the mine, the existing system in shallow part is used to carry out the remining of the stage and section coal pillars of no.11 coal seam by stages and sections. The field practice results show that the remining technology is an effective way to prolong the service life of the aging mine and has good economic and social benefits.
