综放顶板垮落及瓦斯治理探析
|
摘要
研究了矿井瓦斯的性质、顶板跨落的机理、采空区三带分布规律、瓦斯爆炸的火源、瓦斯爆炸的防治等问题。在综放顶板垮落时,为有效防止瓦斯事故发生,要严格遵守煤矿各项安全规定,根据煤层的地质条件、采煤厚度、开采速度、顶板岩性、不同顶板垮落方式、不同周期来压步距,确定三带的准确数据,采取积极有效的防范措施,防止瓦斯事故的发生,确保煤矿安全、经济、高效生产。
The characteristics of mine gas,the mechanism of roof falling,the distribution of three zones in goaf,the source of gas explosion and the prevention and control of gas explosion are studied. In order to prevent gas accidents effectively,the safety regulations of coal mine should be strictly observed. According to geological conditions of coal seam,mining thickness,mining speed,roof lithology,different roof caving modes and different periodic weighting steps,the accurate data of three zones should be determined,and positive and effective preventive measures should be taken to prevent gas accidents and ensure coal mine safety.
