杭来湾煤矿塌陷区地面沉降监测方案设计

为了安全、合理地留设保护煤柱,解放压煤量、节约煤炭资源,开展了塌陷区地面沉降监测方案设计。详细介绍了杭来湾煤矿地面沉降监测点的设计方案、观测内容、观测方法以及观测仪器的精度,并说明了通过后续沉降观测值的数据分析预期能达到的结果等。评价塌陷区稳定性和演变规律,预期可以为矿井大采高综合机械化开采提供生态复垦、保安煤柱设计、资源回收等方面的参考资料,为保障矿井的持续、稳定、高效发展提供借鉴。

Design of land settlement monitoring scheme in the subsidence area of Hanglaiwan Coal Mine

In order to set up protective coal pillars safely and reasonably and improve the recovery rate of coal resources,the monitoring scheme design of land subsidence in the subsidence area was carried out.This paper introduces in detail the design scheme,observation content,observation method and observation instrument of the land subsidence monitoring in Hanglaiwan coal mine,and explains the expected results through the data analysis of the subsequent subsidence observation values.Through the evaluation of the stability and evolution law of the collapse area,it can provide the basis for the mine ecological reclamation,security coal pillar design,resource recovery of mine fully mechanized mining,and provide reference for the sustainable,stable and efficient development of the mine.
