陕西神南矿区煤炭开采保水煤柱留设分析

Analysis of coal pillar for water preserved mining in Shennan Mining Area,Shaanxi Province

陕北榆神府区是我国西部重要的原煤产地,与丰富的煤炭资源比较,水资源贫乏,生态环境脆弱,科学开发利用有限的水资源,促进煤炭基地健康发展至关重要。本文以神南矿区为例,研究了保水采煤保水煤柱留设的科学性,分析了保水采煤的技术措施,提出了针对神南矿区浅埋煤层保水需要而留设保水煤柱尺寸为20～57.2m。

Yushenfu of Northern Shaanxi Province Compared to the abundant coal resources, the wat scientific exploitation and utilization of the limited Under the background of Shennan Mining Area, the preserving technology was analyzed. For water pres range from 20 to 57.2 m in Shennan Mining Area. is the important raw coal producing area in Western China. er resources and ecological environment are poor. Essentially, water resources promote the healthy development of coal base. coal pillar for water preserved mining was studied, and the water erved shallow buried coal mining, the coal pillars are designed
