大采高放顶煤工作面放煤效果好，顶煤回采率高，是今后采煤发展的方向。通过对采用大采高放顶煤开采的工作面的矿压显现进行分析，同时模拟晋兴斜沟煤矿的大采高放顶煤工作面，进行了顶板运动、垮落及支撑力分布的研究，对大采高放顶煤工作面的采场结构有了更深入的了解，为大采高放顶煤工作面的顶板支护及围岩控制提供了技术支持。
大採高放頂煤工作麵放煤效果好，頂煤迴採率高，是今後採煤髮展的方嚮。通過對採用大採高放頂煤開採的工作麵的礦壓顯現進行分析，同時模擬晉興斜溝煤礦的大採高放頂煤工作麵，進行瞭頂闆運動、垮落及支撐力分佈的研究，對大採高放頂煤工作麵的採場結構有瞭更深入的瞭解，為大採高放頂煤工作麵的頂闆支護及圍巖控製提供瞭技術支持。

Put the good effect of coal mining caving coal face, top coal recovery rate is high, the future development direction of coal mining. Through the large mining height of caving coal mining working face of mine pressure behavior analysis and Simulation of Xiegou Coal Mine of mining caving coal working face, the roof movement, caving and the supporting force distribution of Jin Xing, the stope structure has a more in-depth understanding of high caving coal working face with large mining, large mining caving coal working face roof branch support and surrounding rock control provides technical support.
