摘要
为了得出凉水井煤矿顶板导水裂隙的发育规律,首先利用经验公式做了导水裂隙发育高度预测,进而应用野外踏勘实测分析了导裂带发育形态,同时运用数值计算软件FLAC3D进行了导裂带发育过程模拟。
To get the growth rule of Liangshuijing coal mine roof water fractured, first using the empirical formula for the water flowing fracture height prediction, and crack zone development pattern is analyzed by the application of field reconnaissance measured, using numerical simulation software FLAC^3D to simulate crack zone development at the same time.
