摘要
毛坪铅锌矿属构造侵蚀、溶蚀相间的高山峡谷地貌,矿区经过多年开采,形成许多形状复杂和空间分布不确定的古采空区,曾诱发塌陷、山体开裂、崩塌等一系列地质灾害,威胁矿区周边居民及矿山工作人员生命财产安全。本文对毛坪铅锌矿古采空区与地质灾害点空间分布进行了分析研究,总结两者空间分布的规律,古采空区是诱发矿区地质灾害链形成的主要原因,两者在空间位置上关系密不可分。矿山通过采取对古采空区上部塌陷区充填、钻孔注浆固结、充填山体裂缝等治理措施,有效治理了矿山因古采空区诱发的一系列地质灾害,保障了矿山安全生产的同时,也有效保护了矿山工作人员及周边居民生命财产安全。
Maoping lead zinc mine is a mountain canyon landform with tectonic erosion and dissolution.After years of mining,many ancient goafs with complex shape and uncertain spatial distribution have been formed in the mining area,which has induced a series of geological disasters such as collapse,mountain cracking and collapse,threatening the life and property safety of residents around the mining area and mine staff.This paper analyzes and studies the spatial distribution of ancient goaf and geological disaster points in Maoping lead zinc mine,and summarizes the laws of their spatial distribution.Ancient goaf is the main reason for the formation of geological disaster chain in the mining area,and the relationship is inseparable in spatial position.The mine has effectively controlled a series of geological disasters induced by the ancient goaf by taking treatment measures such as filling the collapse area in the upper part of the ancient goaf,drilling grouting consolidation and filling mountain cracks,which not only ensures the safe production of the mine,but also effectively protects the life and property safety of mine staff and surrounding residents.
