落掌煤矿C2煤层瓦斯赋存规律研究和分布预测

Basing on geological structure evolvement and structure distribution characteristic in Luozhang coal mine, analyzing the factors of gas occurrence regularity, finding out the law of gas-geology in Luozhang coal mine, the thesis holds that coal depth is the leading factor of absolute gas emission quantity of coal C2, while gas occurrence is affected locally by coal quality, lithology of coalseam roof and floor and other factors. Gas distribution regularity has been predicted. The research lays a foundation for integrated control of gas disaster in Luozhang coal mine.
