摘要
通过对涡北煤矿深厚冲积层下软岩层地段开拓、准备、回采巷道在不同时期、不同地段,采用不同支护类型和技术参数选择,分析研究巷道来压显现、变形规律,合理确定深厚冲积层下软岩层地段巷道支护类型和技术参数,提高井巷工程质量和服务年限,为新矿区合理开发提供参考依据。
By vortex North coal mine deep under alluvial soft rock Lot development, preparation, mining roadway at different times, different lots of different types of support and technical parameters of selection, analysis of roadway to pressure behavior, deformation law, rationally determine the deep alluvial Lot of soft rock layer under the roadway support the type and technical parameters, to improve the quality of underground works and length of service for the new mining area to provide reference for the rational development.
