Research on characteristics and comprehensive utilization of kaolin resources in coal measure in Henan Province
Coal is the basic energy source in China,and there are kaolin(clay)with large reserves in the coal measures,strengthening the comprehensive utilization of coal measures associated mineral resources is in line with the major needs of national energy resources processing and utilization.Regarding the low comprehensive utilization of kaolin minerals in major mining areas in Henan Province,the geological characteristics and distribution law of kaolin in coal measure strata in Henan Province were analyzed,and the physical and chemical characteristics of kaolin rock in coal measure strata were described across the study of the results of X-ray,differential thermal analysis and scanning electron microscope of the samples,and pointed out that the hard kaolin in the mudstone of the upper Benxi For-mation and central part of Taiyuan Formation and upper part of Shanxi Formation and lower Shihezi Formation is stable and better grade.At the same time,combined with the current utilization of some kaolin processing plants in the province,and through the experi-ment of producing calcined of the kaolin,it was considered that kaolin rock of coal measure strata in Henan Province can be used to pro-duce paper coating and rubber plastic series products,which can provide the utilization direction for the green comprehensive develop-ment of beneficial associated mineral resources for coal mine enterprises.
