摘要
为了减少中厚煤层矿井预留煤柱,研发了沿空留巷开采技术。在此基础上,阳煤集团新元公司3413综采工作面辅助进风巷采用了巷旁充填沿空留巷开采技术,节省了能源,提高了生产率,缩短了准备时间,缓解了采掘接续紧张的局面。
In order to reduce the reserved coal pillars in medium and thick coal seams, gob-side entry retaining mining technology was developed. On this basis, the auxiliary air entry roadway of 3413 fully mechanized mining face of Xinyuan Coal Mine Group adopts the technology of filling and retaining roadway along gob, which saves energy, improves productivity, shortens preparation time and eases the tension of mining continuity.
