摘要
以西铭矿3号煤层实际地质条件为工程背景,通过理论计算,对煤层顶板结构进行合理推断,对顶板来压步距和来压强度进行预测,并为支架选择合理的工作阻力,防止安全事故的发生,为工作面的正常生产奠定了基础。
Take Ximing coal mine as the engineering background, through the theoretical calculation, the reasonable inference to the structure of roof, the roof weighting interval and to predict the compressive strength, and reasonable working resistance for the stent, prevent the occurrence of safety accidents, has paved the way for the normal production of working face.
