Study on Geological Characteristics and Regularity of Ore Body of Wushishan Deposit in Jiangxi Province and Its Indicative Significance to Mining
Due to the lack of specific studies on sedimentary environment,distribution characteristics and variation rules of ore thickness and grade in the early stage of Wushishan mining area,the lack of local(or detailed)production geological data of ore body restrict the production and development of deep mining area.At the same time,the loss of underground mineral resources is fast,and it is difficult to continue the geological mineral resources,which seriously affects the sustainable development of mining enterprises.Through the detailed study of the ore body control mechanism and geological characteristics of the ore deposit,the relationship between the spatial distribution and change rules of each structural layer and ore in the Late Devonian mining area is gradually revealed,the relevant laws are summarized,and the understanding is improved to better guide the underground production practice of the mine.The results show thatthe two wings of the ore body changes greatly and has the characteristics of asymmetry because of the old and fault structure.Based on engineering exploration and drilling verification,comparison,the occurrence form and characteristics of geological structure in the mining area are further confirmed,and the recognition of the structure is enhanced.The thickness of the ore layer presents the characteristics of thick axis and thin wings,thick in south and thin in north direction,and the ore grade is also positively correlated with each other.It has certain indicative significance to the production development of deep mining area and the planned and systematic production prospecting and mining work.
