深部中厚煤层工作面矸石充填技术理论研究

Theoretical research on gangue backfilling technology of work face in deep medium and thick coal seam

以王楼煤矿三采区13313充填工作面为研究背景,通过对三采区地质采矿条件的分析,根据地表村庄和建筑物分布状况,依据煤层开采地表移动变形规律,对工作面充填开采引起的地表沉陷影响进行了预测与分析.提出了工作面充填开采设计方案,采用矸石充填的开采方法,以达到经济、合理、安全地采出建筑物下煤炭资源的目的.

Taking the 13313 filling work face in No. 3 mining area of Wanglou Mine as the research background, through the analysis of geological mining conditions in the mining area, according to the distribution of the surface villages and buildings and the laws of surface movement and deformation of coal mining. The influence of surface subsidence caused by backfilling was predicted and analyzed. The design scheme of backfilling and mining in work face was put forward, and the mining method of gangue backfilling was adopted to achieve the purpose of economical, rational and safe mining of coal resources under the buildings.
