| 摘 要： | 矿井瓦斯是当前影响煤矿安全生产的主要灾害因素,如何在矿井设计、建设前,建立一个比较可靠的矿井瓦斯涌出量预测方法,较准确地预测矿井瓦斯涌出量是一项重要工作。基于分源预测法,结合多年工作实践,建立了勘查阶段结束时,从整个井田及井田历史角度出发的矿井瓦斯涌出预测方法。根据瓦斯地质来源将其划分为邻近层瓦斯涌出、采出煤瓦斯涌出、井下残留煤瓦斯涌出、围岩瓦斯涌出、井田周围煤层瓦斯涌出等5类瓦斯源,并分别建立了相对应的预测公式。通过实例应用,证明该方法有一定的可靠性。

| Abstract: | Mine gas is main disaster factor to impact coalmine safety production at present. It is very important to establish a rather reliable and correct outflow of mine gas prediction method. Based on sourcing prediction method combined with practices in many years, established a mine gas outflow prediction method come out from whole minefield and minefield historic point of view at the end of exploration. Based on five gas source types of neighboring seam, coal winning, underground residual coal, surrounding strata and minefield periphery gas emissions and corresponding prediction formulae have established. Through practice, we illustrated that the method is reliable to a certain extent. |
