摘要:
结合郜城煤矿13191回采工作面的地质条件,建立滑动构造作用下及正常情况下的回采工作面数值计算模型,比较研究了回采过程中的支承压力、垂直位移等矿压规律。计算结果表明:滑动构造作用下,工作面超前支承压力峰值所在位置比无构造时远得多,但应力集中系数较低,工作面前方的煤岩体破坏范围大;随着工作面的推进,采空区顶板下沉量和工作面前方顶板中的反弹值逐渐增大,反弹峰值距煤壁的距离为4~6 m,和周期来压步距基本一致。最后,提出了滑动构造条件下回采工作面安全开采的管理技术措施。
Abstract:
According to geological condition of 13191 miming coal face of Gaocheng coal mine, two numerical simulation models on conditions of gliding tectonics and normal stratum were built. Abutment pressure and vertical displacement were analyzed. Numerical calculation shows that peak positions of abutment pressure of gliding structure was farther than that of normal stratum, and great extent of damage of surrounding rock was generated, but stress concentration factor was lower. Vertical displacement of roof in goaf and rebound displacement ahead mining face were gradually increasing. The distance from mining face to position of peak value of rebound displacement was 4 to 6 meters, which was basically same as periodic roof weighting pace.Finally,technical measures of safe mining were proposed under the condition of gliding tectonics.
