金庄陷落柱伴生黄泥带发育特征及成因探讨

In order to study the developmental characteristics and the genesis of the yellow ground under Jinzhuang mine , research the influence factors of yellow ground development comprehensively and discuss its genetic model, we can use ways of geological survey, collection sample and analysis of whole rock constituents of on and underground . Results show that the development of yellow ground is a geological phenomenon associated with collapse column , which is horizontal distribution ,the scale of hundreds of square meters to thousands of square meters and its lithology mainly is the soft damp gunk; the lithology of yellow ground is mudstone or argillaceous sandstone by sample test and analysis determining; the formation model is as follows: under the effect of water controlling of the landscape and construction as well as water guiding of collapse column, surface water and groundwater permeate through the 9 coal seam, under certain conditions, the mudstone or sandy mudstone of the 9 coal seam roof and floor is oxidized into yellow ground.
