摘要
为解决王庄煤矿煤体强度低,湿润性较差,注水降尘效果不好的问题,采用实验手段对煤体含水量与注水方式的关系进行分析,采取深孔高压注水技术,使工作面回采过程中的粉尘含量大幅度降低,取得了较好的降尘效果。
Aiming at the problems of low coal mass strength, poor wetting and inefficiency of water injection dust, the paperanalyzed the relationship between water content and water injection mode of coal mass by experimental means and put forwarddust removal technology for deep-hole water infusion, which significantly reduced dust content in the mining process of face andachieved a better dusffall effect.
