摘要
通过工作面跨巷开采,掌握炮采工作面矿压显现规律;确定工作面回采对底板大巷的变形规律及超前影响范围;分析底板巷道支护方案的合理性,为今后巷道支护方案优化及工作面垮大巷开采提供可靠依据。
By overhead mining in working face, the paper mastered strata behavior rules of blasting face, deter mined deformation laws on roadway floor and leading impact area, and analyzed the rationality of supporting scheme on roadway floor,which provided a reliable basis for the future roadway supporting scheme optimization and overhead mining in working face.
