摘　　要：为安全开采邯邢矿区深部煤炭资源,提出了"区域超前治理"奥灰岩溶水害理念,开展了华北型煤田大采深高承压水安全开采成套技术研究课题;从理论上研究得出"分带分时段突破"底板突水机理;采用阻水系数法评价试采区底板隔水层承压能力;成功地研究出地面多分支近水平定向钻探关键技术;从岩石力学和水动力学阐述了裂隙含水层中水平孔注浆浆液扩散机理,并给出了孔距计算公式;对于钻遇岩溶或断裂构造状况,研究出了铺底浆液控制技术。地面区域超前治理奥灰水害成套技术在九龙矿成功应用,取得了显著技术经济与环境效果。In order to safely mine the coal resources in the deep depth of Hanxing Mining Area,an idea on the＂regional advance control＂of Ordovician limestone water disaster was provided and a research program was conducted on the completed technology of safety mining in the seam with the deep depth and high pressurized water in North China coalfield. From the theoretical study,the floor water inrush mechanism with ＂zoning and timing section breaking＂was obtained. A water resistance coefficient method was applied to evaluate the pressure bearing capacity of the water isolated layer in the floor of the trial mining block. The key technology of the multi branch subhorizontal directional drilling exploration on the surface ground was successfully researched. From rock mechanics and water dynamics,the paper stated the grout diffusion mechanism of the horizontal borehole grouting in the crack aquifer and provided the calculation formula of the borehole space. When the drilling operation was in the Karst or broken tectonic conditions,a control technology with a bottom grout was researched.The advance completed technology to control the Ordovician limestone water disaster in the surface region was successfully applied in Jiulong Mine,which showed obvious technical and economic effect as well as the environment effect.
