| 摘 要： | 寺家庄煤矿15104工作面是阳泉矿区首个大采高综采工作面，为了了解工作面矿压规律，对15104工作面进行了现场矿压实测与分析，结果表明，工作面初次来压步距为35.8m，周期来压步距为17.9m，动载系数为1.48，工作面中部来压超前于两端1~2m，支架初撑力偏低。实测结果对相同条件下煤层开采具有实践指导意义。

| Abstract: | No.15104 coal mining face in Sijiazhuang Mine was the first fully mechanized high cutting coal mining face in Yangquan Mining Area.In order to understand the mine pressure behavior law of the coal mining face,a site mine pressure measurement and analysis were conducted in No.15104 coal mining face.The results showed that the initial roof pressurized distance of the coal mining face was 35.8 m,the periodical roof pressurized distance was 17.9 m,the dynamic load coefficient was 1.48,the roof pressurized at th... |
