摘要
根据宏松煤矿地质构造和开采标高,划定了M17煤层的测定范围,介绍了测压方法的选择、测压地点的确定,并对影响压力大小的因素进行了分析。在测定范围内准确有效的测定出了M17煤层的瓦斯压力,为宏松煤矿M17煤层煤与瓦斯突出危险性鉴定提供了重要参数。
According to the geological structure and mining elevation of Hongsong coal mine,determining range was delimited in M17 coal seam.The paper introduced the selection about pressure measuring ways and pressure measuring sites,and analysed the factors that affect the gas pressure;detected the gas pressure in M17 coal seam accutately and efficiently in the determining range;provided important parameters for the identification of coal and gas outburst in Hongsong mine.
