复杂建筑群下煤矿采动影响关系评价

Evaluation on Mining Influence Relation under Complex Buildings

依据朝川煤矿一井己三采区"三下冶开采的实际地质条件,设计了全采、条采、部分全采、充填开采等4种开采方案,并对4种开采方案的采动影响进行分析评价,经过方案对比,考虑开采技术成熟度、采后沉降对环境的影响、资源回收、经济效益等多方面因素,推荐采用充填开采方案。

Four mining schemes of full-seam extraction, strip extraction, partial full-seam extraction and extraction with stowing were designed according to the actual geological conditions for coal mining under buildings, railways and water-bodies in No. 3 mining district of Chaochuan No. 1 shaft, analysis and evaluation on the mining influence of four schemes were carried out. Through the comparison of these schemes and in consideration many factors such as the ripeness of mining technology, the influence of mining subsidence upon the environment, resource recovery, economic benefit and so on, it is recommended to adopt the scheme of extraction with stowing.
