掘进工作面高压注水防突措施研究

Research on outburst prevention by high pressure water injection at driving face

以河南大新煤矿为例,阐述了高压注水防突机理,介绍了高压注水防突措施实施方法及防突效果。大新煤矿采用高压注水防突措施后,明显缩短了措施执行时间,简化了措施工艺,提高了掘进速度,降低了掘进成本。

Taking Daxin Coal Mine as an example, the outburst prevention mechanism by high-pressure water injection was described, the detailed high-pressure water injection measures for outburst prevention and the obtained achievements were introduced. The high-pressure water injection shortened the time for outburst prevention and simplified the process so that the driving rate was enhanced and the cost was lowered,
