广东石人樟钨矿矿山采矿塌陷区提取及成果应用

Extraction of mining subsidence area and its application in Shiren Zhang Tungsten mine,Guangdong

地裂缝、塌陷坑是塌陷区的两个重要要素,根据两期Spot6遥感影像判读解译,对地下开采矿山塌陷区进行遥感监测,圈定两期影像矿山采矿造成的采矿塌陷坑、地裂缝,运用两期遥感影像建立三维视图,直观展示塌陷坑、地裂缝,通过对比两期影像圈定的图斑,计算出塌陷坑面积、地裂缝长度及其变化,综合分析塌陷发展趋势,圈定该矿山塌陷区范围,及时为有关部门对矿山环境进行整治提供依据和技术支撑,同时也为该矿区生态环境的综合治理提供基础数据和科学依据。

Ground fissures and collapse pit are two important elements of subsidence area,according to two phase Spot6 deciphering of remote sensing image interpretation,to remote sensing monitoring of underground mining in mining subsidence,select two image mining subsidence caused by mining pit,ground fissure,using two phase of the remote sensing image based 3 d view,intuitive display of sinkhole,ground fissure,by comparing the two figure spot of image and calculate the sinkhole area,ground fissure length and its changes,development trend of the synthetic analysis of subsidence,delineating the scope of mining subsidence,timely provide the basis for relevant departments on mine environmental regulation and technical support,At the same time,it also provides basic data and scientific basis for the comprehensive management of ecological environment in the mining area.
