无预掘巷道倾斜长壁对拉百万吨工作面的开采

Mining of No-Beforehand-Dig Roadway of Dip Long-Wall Megaton's Double-Unit Faces

根据双阳矿的实际地质条件 ,采用倾斜长壁仰斜开采 ,并实现了随采随掘随留巷的无预掘巷技术 。

According to actual geological condition of Shuangyang Coal Mine, up-dip minging of dip long-wall is adopted to realize the technique of no-beforehand-dig roadway, with mining, with digging and with retained gob-side entry. Obvious technique progress and higher economic benefit are obtained.
