根据对南桐矿务局砚石台煤矿4603直线长壁采煤法工作面的现场测试,推导了该工作面顶板的位态方程和临界工作阻力,并从能量释放的角度研究了工作面周期来压的预测指标。
According to the on-site test of 4603 straight longwall coal mining face of YanTaiTai Coal Mine, Nantong Mining Bureau, the attitude equation and critical working resistance of the roof of the working face are deduced. From the angle of energy release, To predict the pressure.
