摘要
分析了水力冲孔技术强化增透机理,并在淮南矿业集团潘北矿进行了底板抽采巷水力冲孔强化增透实验。系统地分析了冲孔水压、冲孔时间、钻孔仰角等技术参数与出煤量的关系,并分析了出煤速度与水压的关系。
Analyzes the mechanism of intensified increasing permeability by hydraulic flushing boreholes technique,and on-site experiments are carried out in Panbei coal mine of Huainan mining group. The relationship between the amount of flushing-out coal and flushing water pressure,flushing time,the angle of borehole is systematically analyzed. And the relationship between the rate of flushing-out coal and water pressure.
