摘要
根据盖州煤业9#煤层围岩地质力学条件,现场钻孔取芯实验室进行力学试验,通过理论计算,结合工程类比法确定支护方案,提出切实可行的安全技术措施。结果表明,巷道的顶板下沉量较小,满足工程实际要求,有效地解决了破碎泥岩顶板开切眼支护难题。
Based on surrounding rock geomechanical conditions of 9# seam in Gaizhou Coal Industry, mechanical tests performed in filed core-drilling method laboratory, and theoretical calculations, this paper propose practical measures for safety technology combined with engineering analogy method to determine support program. The results showed that roof roadway squat is smaller, which can meet the engineering requirements and effectively resolved open-off cut support problems in broken mudstone roof.
