不同开采条件下煤层底板破坏深度的测试研究
Test Study on Coal Seams Floor Destroyed Deepth under Different Mining Condition
【摘要】 邢台矿的 9#煤层 ,占矿井储量的 66 %以上 ,但受奥灰水的威胁 ,列为D级储量。现用注水试验的方式 ,测试了不同开采条件下 2 #煤层的底板破坏深度 ,导出了底板破坏深度的计算公式 ,因 2 #煤层与 9#煤层的底板相似 ,故为 9#煤层带压开采提供了科学依据。
【Abstract】 Coal reserves is over sixty-six precent in 9 # coal seam Xingtai coal mine,but it is D grade reserves beacuse of ash water,this paper introduces test of water flooding,test floor destroyed deepth of 2 # coal seam under different mining condition,it reachs count formula of floor destroyed deepth,2 # coal seam is simular to 9 # so it provides scientific basis.
