摘要
瓦斯涌出是威胁煤矿安全生产的主要因素之一。在新矿井、新水平和新采区投产前,都应进行矿井瓦斯抽放,确定合理的钻孔抽放间距是提高瓦斯抽放率和确保工作面安全生产的关键。利用MATLAB对五虎山煤矿1201工作面钻孔的抽放半径进行数值模拟来取得合理的钻孔间距,为确保瓦斯的抽放效果提供了科学依据。
Threat to the coal mine safety production is one of the main factors of gas emission.Therefore,in the new mine、 new level and new mining before production, Should be for mine gas drainage, to determine reasonable drainage drilling spacing is the key for Improve the gas drainage rate and ensure the working face of production safety, In this paper, the 1201 working face in Wuhu shan mine drainage radius of numerical simulation to determine the reasonable hole spacing use of MATLAB, in order to guarantee the effect of drainage gas to provide scientific basis.
