东滩煤矿3204工作面变形观测站综合分析

Comprehensive analysis of deformation observation station in 3204 working face of Dongtan coal mine

东滩煤矿拟开采东翼三采区的3204综采工作面,该工作面东北部为北宫村。3204工作面已进入村庄煤柱,井下煤层的开采将会对地表村庄房屋造成一定影响。在搬迁未实施之前,为了保证矿井正常开采,在3204工作面开采时,了解区域地质采矿条件下地表移动变形状况,保证地表建(构)筑物的安全使用,并通过观测的数据,分析地下开采对地表村庄房屋的影响规律,以更好的指导其它类似工作面的开采方案,在此区域建立了地表移动观测站。

The 3204 fully mechanized mining face in three mining area of East Wing in Dongtan coal mine is north-east.3204 working face has entered the village pillar,underground coal seam mining will have a certain impact on the surface of village houses.Before the relocation,in order to ensure mine normal mining,in 3204 working face mining,to understand the regional geology and mining conditions of surface movement deformation,to ensure the safe use of surface building（construction）,and through the observation of data,analysis of underground mining on the impact of the village houses on the law,In order to better guide other similar mining schemes,a surface mobile observatory has been established in this area.
