摘要
本文模拟研究了南桐煤矿地质构造应力分布与煤和瓦斯突出的关系。根据实验结果,作者认为反映煤与瓦斯突出的主要地质构造应力指标是最大弹性潜能和最大剪应力,煤与瓦斯突出的地质特征是煤层中的'软分层'。
In this paper, the relation between distribution of tectonic stress and outburst of coal and gas in Nantong Colliery is investigated in simulation tests. Based on the results, the author considers that the main indices of tectonic stress which represent the possibility of coal-gas outburst are maximum elastic potential energy and maximum shear stress; and that the geological feature for forecasting outburst of coal and gas is 'the soft and weak layers' in coal seam.
