Abstract: Jinchuan nickel mine is famous for its thick and deep buried ore bodies,high ground pressure and broken rock in the mining circles.Along with our country's rising demand to the nickel resource,the scale of resource development is increasing rapidly.At present,the mine production capacity is close to 9000000 tons,and increases at an annual rate of 10%.The deposit mining is near 1km,the ground pressure of stope appeared severely,thus,it bring to the stability of mine engineering and strata control great difficulties;To this end,Jinchuan nickel mine has repeatedly carrying out the regularity of the activity of stope ground pressure,support technology,filling technology and ground pressure control and other major technology research.The research revealed a rule of ground pressure pattern of activities of filling stope,realized the effective control of stope ground pressure and continuously mining in big area.With the depth of Ore deposit exploitation increasing and the area expanding,the problem of ground pressure control is more and more serious,and the control to the stability deep roadway engineering is also more difficult.In especial,the mine production capacity increases year by year,which brings more challenge to the safety,high efficiency and economic exploitation of mine.In view of the domestic and foreign development of nickel resource situation and the difficulties mining faced,Jinchuan nickel mine is striving to make the second round technological breakthrough to the resource exploitation in Jinchuan.especially the study on comprehensive utilization of solid wastes mine resources,the development of low cost and high strength new filling cementitious material to reduce the cost and improve the efficiency.
