摘要
分析了东荣二矿17#煤层采准巷道动压形成原因及响应影响因素,通过对该矿原有支护方案下动压巷道的围岩变形观察,分析了动压影响规律,针对17#煤层采准巷道动压的安全掘进提出了合理的支护方案,通过现场工业实验得到了理想的控制效果,进一步说明了动压巷道的支护关键所在。
Analysis the cause of kinetic pressur formation and the influence factor in the stoping drift, analysis the influence regular of kinetic pressur by espial surrounding deform of kinetic pressur roadway with inherited support version. Bring justifiability support version up with stoping drift safety tunnelling of 17# coal seam, make perfect control effects by the scene commerical test, and further analogise the support point with kinetic pressur roadway.
