【摘要】：為了確定12采區(qū)安全煤巖柱留設(shè)類型。基于趙家寨礦12采區(qū)東翼松散層水文及地質(zhì)勘探資料,結(jié)合抽水試驗(yàn)數(shù)據(jù)和計(jì)算含水層參數(shù)的Theis公式,研究了松散層厚度分布及松散層含(隔)水層的垂向變化規(guī)律,特別是松散層底部含水層的水文地質(zhì)參數(shù)特征。結(jié)果表明,12采區(qū)松散層厚度變化受古地形控制,垂向具有多層復(fù)合結(jié)構(gòu),含水層連續(xù)性較差,底部含水層富水性為弱到中等,水體采動(dòng)等級(jí)大部分屬于Ⅱ級(jí),局部屬于Ⅰ級(jí),為留設(shè)安全煤巖柱類型提供了科學(xué)依據(jù)。
[Abstract]:In order to determine the type of safe coal pillar in 12 mining area. Based on hydrological and geological exploration data of loose bed in the eastern wing of Zhaojiazhai Mine No. 12 mining area, combined with pumping test data and Theis formula for calculating aquifer parameters, the distribution of loose layer thickness and the vertical variation law of loose layer containing (separating) water layer are studied. In particular, the hydrogeological parameters of the aquifer at the bottom of the loose layer. The results show that the variation of loose layer thickness is controlled by paleotopography, vertical multi-layer composite structure, poor continuity of aquifer, weak to medium water rich in bottom aquifer, most of the water mining grade belongs to class 鈪，
