焦作市九里山煤矿塌陷区变化趋势遥感分析

Remote Sensing Analysis of Change Trend of Jiulishan Coal Mine Subsidence Area in Jiaozuo City

煤矿生产导致的塌陷不仅严重影响当地居民的正常生活,而且破坏生态环境,监测塌陷区的变化特征和发展趋势,是进行防治的关键。本文通过三期遥感数据,运用ENVI和Arc GIS软件对焦作市九里山煤矿塌陷区的变化特征和发展趋势进行解译分析,认为:(1)九里山煤矿塌陷区逐步扩展,2012年主要集中于西部区域;(2)塌陷区面积2000年为94.45 hm^(2),占矿区面积的5.06%,到2019年达到463.42 hm^(2),占矿区面积的24.84%,增加幅度非常大,说明矿区塌陷进入高发阶段;(3)2000年到2012年的变幅为82.15%,2012年到2019年的变幅为169.37%,2000年到2019年的变幅则达到390.65%,整体呈现急剧增加趋势,未来发展将更加严重。

The collapse caused by coal mine production not only seriously affects the normal life of local residents,but also destroys the ecological environment.Monitoring the change characteristics and development trend of the collapse is the key to the prevention and control.Based on three periods of remote sensing data and ENVI and ArcGIS software,this paper interprets and analyzes the change characteristics and trends of JiulishanCoal Mine subsidence area in Jiaozuo City.It is considered that:(I)the distribution area of collapse area in Jiulishan mining area has gradually expanded,and it is mainly concentrated in the western region in 2012;(2)The subsidence area was 94.45 hm^(2)in 2000,accounting for 5.06%of the mining area;By 2019,it will reach 463.42 hm^(2),accounting for 24.84%of the mining area,with a very large increase,indicating that the mining area has entered a high incidence stage of collapse;(3)The range from 2000 to 2012 is 82.15%,from 2012 to 2019 is 169.37%,and from 2000 to 2019 is 390.65%.The overall trend is a sharp increase,and the development will become more serious in the future.
