摘要
伴随着经济发展,矿产资源开发形成了大量地下采空区,部分采空发生了地裂缝、地面沉降及地面塌陷等地质灾害。为了能够精准指导地下采空区治理,消除采空区地质灾害隐患,可采用三维激光扫描技术进行采空区现状勘查,清晰反映采空区规模及空间分布。以滦平县某铁矿为例,选取10号钻孔开展三维激光扫描,确定了采空区规模、分布范围坐标及埋深情况。为滦平县某铁矿采空区的治理提供了数据支持,为同类采空区的勘查工作提供了技术参考。该勘查方法具有数据精确、工作高效、成果直观等优点,对采空区的勘查具有极大指导意义。
With economic development,a large number of underground mined out areas have been formed in the development of mineral resources,and some mined out areas have occurred geological disasters such as ground fissures,ground subsidence and ground collapse.In order to accurately guide the treatment of underground goaf and eliminate the hidden dangers of geological disasters in goaf,three-dimensional laser scanning technology can be used to investigate the current situation of goaf and clearly reflect the scale and spatial distribution of goaf.Taking an iron mine in Luanpingcounty as an example,borehole 10 was selected to carry out three-dimensional laser scanning,and the scale,distribution range,coordinates and buried depth of the goaf were determined.It provides data support for the treatment of a mined out area of an iron mine in Luanpingcounty,and provides a technical reference for the exploration of similar mined out areas.This exploration method has the advantages of accurate data,high efficiency and intuitive results,and has great guiding significance for the exploration of goaf.
