| Abstract: | The Xinjie minefield is situated at northwest of Qinzheng city of Guizhou Province.The No.9 coal seam of it possesses identified coal resources 64.05 million tons,potential coal resources 12.78 million tons.Coal in No.9 coal seam has striped structure,quasi-glass luster,conchoids and splintery fracture,endogenous and exogenous fractures developed,is moderate grind-able coal.Macroscopically coal type is semi-dark to semi-bright coal.Micro coal type is inert coal.Coal quality belongs to low to medium ash,medium sulfur,high calorific value,low volatile matter,low phosphorus,easy grind-able,extra-low chlorine,coal type belong to anthracite No.3.It can be in use for power-station coal and domestic coal. |
