摘要
以河南新能开发有限公司王行庄煤矿为研究背景,介绍了保护层开采理论,考察了采取保护层开采措施前后同一测试地点的瓦斯参数,主要包括瓦斯含量、瓦斯压力、煤层的透气性系数及突出预测指标。现场试验结果表明,采取保护层开采措施后,被保护层区域瓦斯压力及含量大幅降低,瓦斯涌出量及突出预测指标明显下降,煤层透气性系数大幅增加。
The paper took Wangxingzhuang Coal Mine of Henan New Energy Development Co.,Ltd.as research background,introduced protective seam mining theory,and investigated gas parameters in the same test site before and after taking protective layer mining measures,including gas content,gas pressure,coal seam permeability coefficient and outburst predictive index.Field test results show that after taking protective layer mining measures,gas pressure and content of the protected layer region reduce significantly,the gas emission amount and outburst predictive index decrease obviously,and seam permeability coefficient increases greatly.
