摘要
吴寨矿己17煤层与具有突出危险性的矿井十矿、十二矿相邻,采掘延伸达到或超过垂深50m时必须确定煤层的突出危险性。根据地质资料和实测数据,结合邻近矿井瓦斯动力现象,应用单项指标对吴寨矿己17煤层进行了瓦斯突出危险性研究。结果表明,在标高-450m以浅,吴寨矿西翼采区己17煤层无煤与瓦斯突出危险性。
Caproic17 coal seam of Wuzhai Mine is adjacent to the outburst dangerous tenth mine and twelfth mine,mining extensions meet or exceed the vertical depth of 50m must determine the risk of coal outburst.According to the geological data and measured data,in combination with the gas dynamic phenomena of neighboring mines,by using individual indicators Wuzhai Coal Mine Caproic17 conducted to study the risk of gas outburst.The results showed that the elevation of-450m to light,Caproic17 seam of Wuzhai Mine the west wing has not the risk of coal and gas outburst.
