摘要
采用理论分析和数值模拟的方法,研究了多点控制水力压裂增透消突的机理,研究发现:控制孔对压裂孔的起裂与扩展具有导向和卸压作用,可以有效控制裂隙发展方向,降低对水力压裂注水泵的设备要求,最后在鹤煤六矿2143下顺槽掘进工作面和2143集中巷进行了现场压裂应用,抽采效果得到明显提高。
Multipolnt control hydraulic fracturing mechanism used for increasing permeability and eliminating outburst is researched by theoretical analysis and numerical simulation.The control hole has the impact of guiding and pressure release on the crack initiation and extending of fracturing hole, it can control the fracture development direction effectively, lowering the pressure request of water injection pump .At last fracturing experiment is carried out in the 2143 heading face and concentrated roadway of Hemei sixth mine, gas drainage effect is improved obviously.
