摘要
瓦斯突出是制约煤矿安全高效生产的重要因素,但开展瓦斯治理工作过程中多侧重于发展新型钻孔抽采技术,忽略了瓦斯地质特征对瓦斯治理的影响,结合瓦斯地质特征对瓦斯抽采方案进行优化能够有效实现煤矿瓦斯的精准控制。基于此种情况,从地质构造特征、煤层埋深、煤层厚度3个方面分析了煤矿瓦斯地质特征,揭示了区域煤层的成因及对瓦斯突出的影响;总结了区域瓦斯突出的常见位置、强度及类型;结合不同采煤工作面特点开展了多种瓦斯治理措施,实现了煤矿的安全开发。
Gas protrusion is an important factor restricting the safe and efficient production of coal mines,but the process of gas management mostly focuses on the development of new drilling and extraction techniques,ignoring the influence of gas geological characteristics on gas management.Based on this situation,the geological characteristics of coal mine gas are analyzed from three aspects:geological structure characteristics,coal seam depth and coal seam thickness,which reveal the causes of regional coal seams and their influence on gas protrusion;the common location,intensity and types of regional gas protrusion are summarized;various gas management measures are carried out in combination with the characteristics of different coal mining working faces to realize the safe development of coal mines.
