摘要
针对曙光矿瓦斯与粉尘治理工作中存在的问题,提出首先进行瓦斯抽放、然后利用抽放钻孔进行煤层注水来解决瓦斯与粉尘灾害问题的技术方案。根据曙光矿1214工作面的实际情况,利用FLUENT数值模拟软件对1214工作面进行瓦斯抽采数值模拟,并在此基础上进行了煤层注水模拟。研究表明:曙光矿将瓦斯与粉尘综合治理的技术方案是可行有效的。
According to the problems of gas and dust management in Shuguang Mine, gas extraction can be done first, and then gas and dust disasters can be eliminated by using the rational parameter of hole to infusing coal seam water. Based on the actual situation of 1214 fully-mechanized face about Shuguang mine, numerical modeling the gas extraction and coal seam water infusion by FLUENT. The results show that： this comprehensive scheme of managing the gas and dust is effective and efficient.
