灵台某矿工业场地选择及开拓方案设计

Industrial site selection and development scheme design of a mine in Lingtai mining area

灵台某矿煤层埋藏深,地质条件复杂。根据地形条件及自然灾害、主要用户情况及项目管理、井下煤层赋存情况及勘查程度等因素,对灵台某矿工业场地位置提出了4个方案(达溪河岸陈家湾场地、史家河与蛟城河交汇处的寺沟村场地、塬上冯家山村场地、达溪河岸电厂对面安家庄场地)。同时,结合工业场地位置提出了3个开拓方案。从井巷工程、井下设备、地面工程、外运、运营费、工期、压煤量、运营等方面分别进行了全方位的对比,经过综合分析工业场地位置与开拓方案的关系,最终确定陈家湾主、副立井开拓方案,为灵台矿区类似矿井的设计提供了借鉴。

The coal seam of Lingtai mining area is deep and its geological conditions are complex.According to terrain conditions and natural disasters,main users and project management,underground coal seam occurrence and exploration degree,four schemes are proposed for the location of the industrial site of Lingtai mine,namely,Chenjiawan site on the bank of Daxi River,Sigou village site at the intersection of Shijia River and Jiaocheng River,Fengjiashan village site on the plateau,and Anjiazhuang site opposite the power plant on the bank of Daxi River.At the same time,combined with the location of the industrial site,three development plans are put forward.The comprehensive comparison is made from the aspects of shaft and roadway engineering,underground equipment,surface engineering,outward transportation,operation cost,construction period,coal pillars and operation.Through the comprehensive analysis of the relationship between the industrial site location and the development plan,the development plan of main and auxiliary shafts in Chenjiawan site is finally determined,which provides a reference for the design of similar mines in Lingtai mining area.
