摘要
对单孔抽采影响半径、单排相邻钻孔耦合抽采影响半径和双排相邻钻孔耦合抽采影响半径进行现场试验和考察,研究不同布孔方式下测试孔的流量变化情况,根据流量的变化幅度确定了不同抽采钻孔布置情况下影响半径R与抽采时间t之间的函数关系,为确定合理抽采钻孔参数提供借鉴。
The flow change of instrument connection in different drilling layout was studied by analyzing single hole drilling mining influenced radius,single row adjacent drilling coupling influenced radius and double row adjacent drilling coupling influenced radius change,functional relation of radius R and drilling mining time t were set based on flow change in different drilling layout,the technology provides reference for reasonable drilling parameter.
