摘　　要：为了解决官地煤矿2号煤层开采时,3号煤瓦斯涌入2号煤层造成工作面瓦斯涌出量大、瓦斯浓度易超限的问题,根据2号、3号煤层的地质条件,提出了底抽巷抽采邻近层卸压瓦斯的技术方案,并在官地矿22611工作面进行实施。该方案在3号煤底抽巷两侧施工钻孔,覆盖区域为整个22611工作面下方,并进行瓦斯抽采。结果表明,该方案取得了良好的抽采效果,解决了2号煤层开采过程中存在的瓦斯超限问题。底抽巷抽采瓦斯技术是一种解决邻近层瓦斯涌入有效方法。In order to solve the problem of large gas emission and gas concentration exceeding limit caused by No.3coal gas gushing into No.2 coal seam in Guandi coal mine, according to the geological conditions of No.2 and No.3 coalseams, the technical scheme of extracting pressure-relief gas from adjacent seams by bottom suction roadway was putforward and implemented in No.22611 coal face of Guandi coal mine. The scheme is to drill holes on both sides of No.3 coal suction roadway, covering the whole 22611 working face below, and the gas extraction is carried out. The resultsshow that the scheme has achieved good drainage effect and solved the problem of gas exceeding limit in the process ofNo. 2 coal seam mining. The technology of gas drainage from bottom drainage roadway is an effective way to solve thegas influx in the adjacent area.
