| 摘 要： | 以观台煤矿二水平(-270 m水平)总回风巷掘进头及2403轻放工作面煤层及顶、底板煤岩为研究对象,利用试验机测定并分析其物理力学性质,以此为基础,利用弹性能量指数法评价观台煤矿煤、岩冲击倾向性,最终得出工作面内不会产生冲击地压现象,在以后的工作面回采过程中得到了验证。并建立了观台煤矿煤的冲击倾向性评判标准。

| Abstract: | Regard the coal seam and rock stratum of its roof,floor of-270 level air-return roadway ahead and 2403 working face in Guantai coal mine as the research object.Use the examination machine mensurated and analyzed its physics mechanics quality.Based on this,we using the method of elasticity energy exponent estimate the coal and rock impact orientation of Guantai coal mine.And get the conclusion that there will no rock burst phenomena happen at the working face finally.The conclusion has been verified in the following working face.And we have set up the coal impact orientation estimate standard of Guantai coal mine. |
