摘要
指出了静压注水和动压注水在处理煤层瓦斯的缺陷,进行了高压脉动注水的工业性试验,分析了注水前后煤体水分含量、瓦斯涌出、突出预测、校检指标的情况,试验结果表明,煤层高压脉动注水能较好地防治煤与瓦斯突出。
The paper points out the defects of gas treatment with water injection by static pressure and dynamic pressure. Industrial test was conducted on high-pressure pulse water injection. Water content in coal before and after water injection, gas inrush, outburst prediction, and check index were studied. The test results showed that the high-pressure pulse water injection could better control the coal and gas outburst.
