复杂条件下大采高工作面矿压显现规律研究

针对长平矿井Ⅲ4304大采高工作面复杂条件,对大采高工作面顶板破断特征、支架-围岩关系、矿压显现规律、工作面工艺方式等生产系统进行研究,指导矿井厚煤层安全高效开采,进一步简化矿井生产布局,降低吨煤生产成本,提高工作面单产及采出率,提高工作面安全管理质量,同时为长平矿井推广高效高采出率大采高开采技术提供理论依据和技术经验。

On the Regularity of Mine Behavior of Large Mining-Height Working Face in Complex Conditions

In terms of the complex conditions of Ⅲ4304 large mining-height working face of Changping Mine, the production systems such as the roof breaking features, relationship between support and surrounding rock, regularity of mine behavior, process methods of working face of large mining-height working face are studied to guide the safe and efficient mining of thick coal seams, further simplify production layout of mine, reduce coal production costs per ton, improve per unit area yield and recovery ratio of working face, improve the quality of safety management of working face, and provide theoretical basis and technical experience for the promotion of efficient and high recovery-ratio mining technology for large mining-height working face by Changping Mine.
