摘要
针对中马村矿二1煤层瓦斯含量高,煤层透气性差,抽采衰减速度快的特点,为提高抽采效果,尽快实现煤层消突,在27021工作面回风巷进行了虚拟储层水力压裂,为考察水力压裂影响范围及效果,使用CYT技术进行了压裂异常区探测,并对工作面区域验证指标等瓦斯参数进行统计,对虚拟储层水力压裂起到了较好的增透效果。
TheⅡ1 coal seam in Zhongmacun Mine is characteristic of high gas content,poor permeability,fast decay rate of gas drainage.A virtual reservoir hydraulic fracturing technology was carried out in the return airway of 27021 working face to realize drainage improvement and outburst elimination.In order to investigate the range and effect of hydraulic fracturing,CYT technology was used to detect the fracturing anomaly areas and calculate some gas parameters,including verification index of working face,which has obtained ideal increasing permeability on the hydraulic fracturing of the virtual reservoir.
