摘要
在复杂地质条件下,无煤柱护巷技术需要面对较为棘手的安全隐患问题,所以有必要在支护方面进行深入研究。基于此,开展对急倾斜煤层的沿空护巷的研究,对主要的支护形式、技术特点、安全防护措施等,以及支护中的各项阻力展开分析,旨在从理论层面上对支护技术给予支撑,提出关键措施,为我国煤矿开采技术提供更多的实践价值。
Under complicated geological conditions,technique of gob entry without coal seam faces thorny issues,especially research on necessary protection.Analysis and research on gob entry in steepinclined coal seam,especially by means of main protection form,technique characteristics,safe protection measures,and resistances from protection,are carried out aiming to obtain further understandings from the aspect of protection theory,as to provide practical value for coal mining techniques in China.
