摘　　要：随着矿井生产能力的不断扩大,目前矿井主要生产采区即将回采结束,从衔接时间上,无法满足矿区正常生产的进行,为了矿井的可持续发展,在保证工业广场内现有生产系统正常安全运转的前提下,完成西一采区8-1煤层局部进入工业广场保护煤柱的开采设计方案,分析研究开采后对工业广场内主要生产设施建筑物和邻近村庄的影响程度,并提出相应的维护措施,对解放建筑物下压煤具有较大的实用价值。With the increase of mining productivity, the exploitation of the main mining district will end soon, there doesn＇ t have enough time to make sure the mine can work normally. On the premise that the product system of industry square pillar can work safely and the mine develops sustainably, this paper tends to put forward the mining design for 8-1 coal seam of west first mining distriet, which is locally adopted under the industry square protective pillar. The paper also tries to analysis the influence on the main manufacturing facility and the near towns after mining. Then the maintenance measures are put forward correspondingly. This study has important practical value to the exploitation of the limited mineral resources under the buildings.
