条带顺层钻孔卸压抽采优化布置研究

Optimal Placement of Stripe Bedding Borehole Pressure Relief Extraction Research

针对鹤壁中泰矿业31021综采工作面,利用卸压槽技术和瓦斯抽采技术相结合抽采煤层瓦斯的方法,对现场抽采钻孔进行优化设计,通过一段时间的实时监测数据结果显示,在抽采孔施工期间,抽采浓度及瓦斯抽采量逐渐减少,大大缩短了抽采周期。

In Hebi Zhongtai mining 31021 fully mechanized coal face, by the technique of pressure relief groove and the gas extraction technology of extracting seam gas drainage method, extraction from drilling optimization design on the spot,through a period of real-time monitoring data, according to the results in the extraction hole during the period of construction,the extraction concentration and gas extraction volume daily gradually reduce, greatly shortens the extraction period.
