摘要
煤层瓦斯赋存规律研究和突出区域预测指标的准确选取是确保煤矿安全生产的关键。通过分析新安煤田的瓦斯地质资料,研究该煤田煤与瓦斯突出规律及控制因素,查明该煤田的瓦斯赋存规律,把指标预测法和瓦斯地质方法结合起来,提出以瓦斯含量作为突出区域预测指标并确定其临界值,为新安煤田科学管理、提高经济效益提供技术依据。
Studying on distribution rules of coal seam gas and accurately selecting prediction index of outburst region are the key work to guarantee mine safe production. Based, on gas geology data analysis on Xin＇an coal field,the rules and main control factors of outbursts were studied, and the gas distribution rules were found out. In the end, the method of index prediction and gas geology were combined, and the view of taking gas content as regional prediction indexes, the method of determining critical value was put forward, which provided technique support for Xin＇an coal field＇s scientific management and economic efficiency improving.
