摘要
通过分析老公营子煤矿水文地质条件和覆岩结构类型,采用简易水文法、数值模拟法及类比分析法预计了综放开采的覆岩破坏高度,分析论证了特厚煤层第四系含水层下综放开采的可行性,提出了首采面进行综放试采的开采方案。
Applying simple hydrology method, numerical simulation and analogy analysis method, this paper predicted broken height of overlying strata of full-mechanized caving mining on the basis of hydro-geological condition and structure form of overlying stra- ta. Feasibility of full-mechanized caving mining extremely-thick coal-seam under quaternary aquifer was discussed and mining projection of first mining face was put forward.
