Abstract: In order to study the exploitation design of the mine with a depth of 1000 meters in the thick surface soil layer, and constantly improve the design level, the exploitation system is reasonable, technically advanced and feasible, economically reasonable from the design source, so as to realize the safety, high efficiency and high yield of the modern mine. After analyzing the geological characteristics of Kouzidong mine field, which is characterized by thick topsoil, high ground pressure and deep burial, the exploration design of Kouzidong mine was studied. The research results have certain guiding significance and reference value for the design of similar type mines with thick topsoil, high ground pressure and large buried depth.
