摘要
提出了在石门揭煤中预防瓦斯突出的一种计算钻孔位置的优化方法。目前实际中采用的计算方法很繁杂,计算精度低,而且不能给出最优的钻孔位置。本文引入解析几何,借助计算机对钻孔位置进行较精确计算。采用优化后的方法可以提高瓦斯抽放效果,减少钻孔数量从而节省施工投入。
An optimum method of calculating drilling hole position in preventing cross-measure cutting coal gas burst is put forward. The present applied calculation method is very complicated and low calculating accuracy, and this method can not determine the drilling hole position. In this paper, analytic geometry is drawn into drilling hole position calculation and have the aid of computer, the calculation is accurate. It can improve gas suction effect, reduce drilling hole amount and save construction investment.
