煤层裂隙
煤层裂隙
本文采用煤层断裂破坏指数、变形系数对煤裂隙发育程度进行综合评价,来预测高渗区。
The way and principle of Gaussian curvature method for forecasting natural fracture zones in coal seam are discussed.论述了高斯曲率法预测煤层天然裂隙发育区的基本原理和方法。
Based on laboratory experiments and in-situ observations, it has been proved that outburst of coal and gas in in-seam drivage is a chain reaction process of disc tensile fracture in a working face.本文通过基础试验和现场观测,证明了煤巷掘进工作面煤与瓦斯突出是工作面煤壁盘形拉伸破坏的连锁反应过程。
