薄煤层综采自动化工作面过陷落柱技术

The Fully Mechanized Mining Face Through Subsided Column Technology in Thin Coal Seam

薛村矿94702工作面为薄煤层综采自动化工作面,该面外段回采需要过X6陷落柱。根据对X6陷落柱进行的水文评价,确定其为不导水陷落柱,从而在工作面推采过陷落柱期间,采取合理的开采技术方法,短时间内通过了陷落柱伴生的断层影响区段,节省了重开切眼巷道及二次搬家准备的工程量,为今后矿井回采过类似地质构造区积累了经验和办法。

94702 mechanized mining face of Xuecun Mine was thin automated face, whose outer segment stoping had to go through X6 collapse column. According to the X6 collapse column hydrographic evaluation, anti-conducting water subsided column was decided. Therefore, during collapse column mining face pushing, reasonable mining method was conducted, which resulted in passing the collapse column associated fault influence extents, saving reopening the cutting-hole roadway and the second move preparation of the project and accumulating mine stoping experience and methods in similar geological structure.
