Dashucun Mine, Hebei Jizhong Hanfeng Mining Co., Ltd.

综合分析大淑村矿生产现状，以及现有井下生产系统及五采区实际地质情况，探测采区深部天然焦侵入范围，对照地面村庄与井下采区巷道及回采工作面关系，考虑开采对地面村庄建构筑物影响程度，在充分利用四采区现有生产系统的基础上，避免五采区生产系统不独立，同时研究五采区村庄煤柱下开采技术方案，最终达到了减少掘进准备工程，降低地面建构筑物破坏程度，最大程度解放村庄压覆煤炭资源的目的，准备工期由原来的37个月缩减至15个月。该技术可为其他类似矿井提供借鉴。

Based on the comprehensive analysis of the production status of Dashucun Mine, as well as the existing underground production system and the actual geological conditions of the fifth mining area, the intrusion range of deep natural coke in the mining area was detected. Compared with the relationship between the ground village and the underground mining area roadway and the mining face, the influence degree of mining on the ground village buildings was considered. On the basis of making full use of the existing production system of the fourth mining area, the production system of the fifth mining area was not independent. At the same time, the mining technology scheme under the village coal pillar of the fifth mining area was studied. Finally, the purpose of reducing the excavation preparation project, reducing the damage degree of the ground building structure and maximizing the liberation of the village overlying coal resources was achieved. The preparation period was reduced from 37 months to 15 months. This technology can provide reference for other similar mines.
