摘要
本文通过对陈四楼井田构造特征分析,陈四楼井田的主要控水构造有断层和陷落柱。决定井田边界及采区划分的大中型断层共计34条,其中产生涌水的断层落差在1.5m到95m之间,涌水水源主要是太原组上段(Lll-L8)灰岩水,最大涌水量为35-860m。/h。矿井各陷落柱附近断层构造发育,加剧了陷落柱水文地质条件的复杂性,对矿井安全生产有一定威胁,经过工作面底板注浆改造及综合治理,21301工作面安全回采通过陷落柱。其他两个陷落柱均留设防水煤柱,工作面绕过陷落柱回采。
Based on the analysis of characteristics o! Chen bllou Ida, the mmn floor tour lcia Chen water tectomc mint and subsided column. Decide well boundary and mining area into a total of 34 large and medium - sized fault, the fault throw water ranging from 1.5 - 95m, the maximum yield of 35 ~ 860m3/h, gushing water sources are mainly the upper Taiyuan formation ( L11 N l_g ) limestone water. Mine the collapse column faults developed in the vicinity, exacerbated by the complexity of collapse column hydrogeological conditions, a threat to the safety production of the coal mine, the bottom grouting reconstruction and comprehensive treatment, 21301 face safe mining through other two pillars are waterproof pillar working face mining, bypassing the collapse column. the collapse column after Theother two pillars are waterproof pillar working face mining, bypassing the collapse column.
