天湖山矿区紧密褶皱中的采掘布置

Coal Mining Layout of Compact Folds Structural Feature at Tianhushan Mining Area

福建省永春煤矿南湖一号井,通过生产实践,证实天湖山矿区南湖井田地层多呈线状紧密褶皱构造形态,褶曲幅度小,一般在30m以下,在褶皱形成过程中,因挤压作用,产生了煤层压薄带。运用这个规律,服务于生产,对研究确定适当的采区区段垂高、研究布置块段岩石通风井、留压薄带支撑顶板采煤方法的研究、运用等方面均收到良好的效果。

Take Nanhu No.1 Well in Fujian Yongchun Colliery for instance,and on the basis of production practice,the paper has understood Nanhu mine field formation at Tianhushan mining area： presentations of linear compact folds structural feature,small fold amplitude,below 30m normally,in the fold formation,coal seam thin strip produces because of extrusion.Using this rule to serve the production achieves better efficiency on the research of determination segment vertical height,layout block rock ventilation shaft and thin strip roof supporting mining method.
