摘要
通过对1101工作面高顶抽放钻场抽采参数的相关分析,针对掘进中存在的瓦斯安全、抽采效果不理想等问题,从钻孔参数、钻孔施工、钻场维护等方面提出了相应的措施,提高了高顶钻场瓦斯抽采效果,消除了1101工作面瓦斯隐患。
Based on the 1101 working face top drainage drilling field extraction parameter correlation analysis, according to gas safe, unsatisfactory drilling effect, the corresponding measures of the drilling parameters, drilling, drilling field maintenance aspects were put forward, which improved the effect of the top drilling field gas extraction and eliminated the 1101 working face gas hazards.
