摘要
我国是受水害最严重的国家,奥灰水突水是我国很多煤矿在安全生产中急待解决的问题。山西王家岭煤业集团公司王家岭煤矿就面临着开采9号煤层底板奥灰水突水威胁的安全问题。结合王家岭煤矿实际钻孔数据,运用突水系数法、多层叠加抗压强度比值系数法分别对9号煤层进行突水危险性预测,并进行相互对比,根据计算所得结果得出9号煤层底板易发生突水区。
China is the country which is affected by the most serious flood, and ordovician limestone water layer water-inrush is the problem in the press for solution in many Chinese coal mine. Shanxi Wangjialing coal mine is facing the safety production problem of Ordovician Limestone water layer water-inrush in exploiting number 9 coal panel in the bottom combined with practical borehole data, using water-inrush coefficient method, multi-layer superposition compressive strength ratio coefficient method predict the water-inrush risk of number 9 coal-seam respectively and contrasting each other. According to calculation result draw the water-inrush coefficient zoning map.
