地矿测绘, 2020 当前在我国广袤的土地上,许多煤产区都出现了塌陷的情况,对于采煤塌陷地的治理以及生态环境恢复也就成为人们日益关注的问题。随着GPS RTK(实时动态测量)技术的出现,该技术发展至今已经成为地形测量工程中最常见的技术之一,对于采煤塌陷地的治理测量,其也能够发挥出更大的作用。

工程建设, 2023 小康煤矿位于康平煤田的东北部，隶属康平县东关镇。矿井自投产以来，截止2021年未已先后在北一、西一、南一、南二采区及西三采区共回采了33个工作面。其中，有25个工作面采用的综合机械化一次采全高放顶煤开采方法，煤层最大采出厚度达14.3m（含2煤）。大范围地下煤层开采产生了严重的地表沉陷，雨季沉陷区大面积积水。尤其是在采用综放开采的区域，地表最大下沉达4.5～6.5m，部分塌陷坑常年积水。目前西三采区是2019年经过辽宁省自然资源厅依法由大平煤矿采区边界划归到小康开采边界。w3轨道运输大巷，巷道断面宽4 ...
