摘要
利用现有的先进技术装备和管理水平,采用综采和综放混合开采技术对已采上分层煤体的煤层和上分层煤体两侧的边缘煤柱进行开采,提高了资源回收率,缓解了矿井采掘紧张局面,通过对开采过程各项技术指标进行研究分析,取得了较好的经济和社会效益。
With the advanced technology and administrative level, the coal in the higher slice and coal p/liars is mined with the technology of fully- mechanized coal winning and the combined technology of fully- mechanized coal winning and sub- level caving. The resource yield is increased and the intense mining situation in coal mine is relieved. Comparatively good economic and social effects are achieved by analysis of those technological indicators in the mining process.
