根据实测夏店煤矿8120综放试验工作面支架初撑力、循环末阻力、时间加权平均工作阻力及其分布频率，总结了综放面矿压显现规律。研究表明：工作面平均周期来压步距21.6m，平均动载系数1.67，且综放工作面顶煤的放出导致了控顶距上方顶煤破碎、移动，使得支架初撑力、时间加权平均工作阻力偏低。
根據實測夏店煤礦8120綜放試驗工作麵支架初撐力、循環末阻力、時間加權平均工作阻力及其分佈頻率，總結瞭綜放麵礦壓顯現規律。研究錶明：工作麵平均週期來壓步距21.6m，平均動載繫數1.67，且綜放工作麵頂煤的放齣導緻瞭控頂距上方頂煤破碎、移動，使得支架初撐力、時間加權平均工作阻力偏低。

Based on the measured value of the setting load,the end of the cycle resistance, the time-weighted average working resistance and frequency distribution etc. in 8120 fully mechanized working face, summarized the behavior law of mine pressure in fully mechanized top coal caving face. Research shows that: the average periodic weighting step distance of the working surface is 21.6m, the average dynamic load coefifcient is 1.67, the top coal caving caused the top coal in the face width is broken, mobile, which caused the support resistance, time weighted average working resistance is low.
