水力挤出防突技术在牛马司矿业公司的应用

Application of Hydraulic Extrusion Technique for Outburst Prevention in Niumasi Mining Industry Company

牛马司矿业公司为了提高矿井煤巷掘进速度,在水井头煤矿进行了水力挤出防突技术研究试验。初步确定了该防突技术在水井头煤矿应用的合适参数,并进行了防突效果考察。试验表明,水力挤出防突技术能有效消除该矿井煤巷掘进工作面的突出危险性,达到安全快速掘进的目的。

In order to increase the coal roadway driving speed, Niumasi Mining Industry Company has a study and experiment of hydraulic extrusion for preventing coal outburst by water in Shuijingtou Coal Mine. The reasonable technical parameters of preventing coal outburst were studied, and made an investigation of outburst result as well. The experiment show that the hydraulic extrusion for preventing coal outburst can effectively defend the risk of coal outburst at the coal roadway driving region, which have reached to the purpose of driving safely and quickly.
