摘要

研究开采上限对煤矿开采具有十分重要的意义，它可以最大程度地开采压滞的煤炭资源，缓解当前大部分煤矿采掘接替紧张的局面。以田庄矿N2601工作面为例，根据已有水文地质资料以及邻近矿井资料，分析了开采区充水条件及底部含水层的赋水特性；采用数值模拟方法，根据上覆岩层的塑性应变情况，分析了冒落带与导水裂隙带的高度范围，最后综合数值模拟结果与“三下”开采规程的要求确定了该矿的开采上限。

Abstract

A research on increasing mining upper limit is important for coal mining

which can fully utilize coal resources and release most of the mines from the tension of limited successive exploitation. Based on the hydrologic and geologic data and data of nearby mines

taking the N2601 working face of Tianzhuang Mine for example

water resources of the producing area and water-existing character of the floor are analyzed; based on the plastic strain of the cover rock

the height range of caving zone and water flow fractured zone are analyzed through numerical simulation; finally

the upper mining limit is obtained by synthesizing the numerical simulation and exploitation regulations.
