摘要
随着矿井开采深度的增加,特别是在深部靠近向斜轴部的两翼附近,断层构造发育,围岩破碎,地质应力集中,掘进巷道开挖后变形速度快,前掘后修,影响到掘进巷道安全,更无法形成采煤工作面。鄂庄矿通过对深井应力集中区掘进巷道压力与围岩应力的分布机理进行分析,采取了有效的综合防治措施,取得了较好的支护效果。
With the increase of mining depth mine near, especially in deep to the two wings of inclined shaft department, fault structure development near rock broken, geology, stress concentration, roadway excavation deformation tunneling fast speed, Former dug, affect after roadway excavation repair safety, more cannot form the coal face. Hubei xiezhuang coal tunneling through deep roadway of high pressure and stress distribution mechanism of surround- ing rock stress analysis, adopted effective comprehensive prevention and control measures, and acquired better supporting effect.
