Abstract: The wanghushan sand shale ore for cement proportioning in Chaohu City,Anhui Province,is a monoclinic sedimentary stratiform deposit,and the main ore bearing strata are the Fentou formation and Maoshan formation of Silurian system.In order to discuss the development and utilization conditions of the mine,the geological characteristics and ore body characteristics of the deposit are analyzed in detail.The results show that:①the main ore bearing strata in the mining area are fine sandstone and silty mudstone in the Fentou formation (S2f);②the natural types of the ore are argillaceous siltstone,silty mudstone,fine sandstone and siltstone;③ the mining technical conditions of the deposit belong to the medium type (Ⅱ2) mainly based on the engineering geological conditions;On the basis of the analysis,the preliminary analysis of the development and utilization of the deposit is carried out.It is suggested that the industrial index of the ore body should be properly reduced,which can realize the intensive utilization of resources and expand the resource reserves of the mining area,and provide reference for the later detailed investigation,mine construction and geological prospecting and development of similar mining areas.

Key words: cement proportioning,sand shale ore,geological characteristics of the deposit,development and utilization conditions
