| 摘 要： | 为分析高低压混合抽采对抽采负压的影响,以更好的指导矿井生产过程中瓦斯抽采,将抽采负压作为参考指标,采用对比分析的方法,在资江煤矿进行测定研究,结果表明:高低压分离抽采时,钻孔孔口负压平均11.14 kPa,较高低压混合抽采提高了9.28倍;地面泵负压平均70.25kPa,较高低压混合抽采提高了3.42倍。

| Abstract: | In order to analyze the influence of high-low pressure mixed drainage on drainage negative pressure and to better guide the mine production process of gas extraction,drainage negative pressure was taken as reference index.Adopting comparative analysis method,a determination study of Zijiang coal mine was carried out.The test results showed that negative pressure of borehole under high-low pressure separated drainage status can reach to 11.14 kPa on average,it was increased 9.28 times than that was in high-low pressure mixed drainage status;the negative pressure of ground pump can reach to 70.25 kPa on average,it was increased 3.42 times than that was in high-low pressure mixed drainage status. |
