Abstract: The calculation of the coal and rock amount is an important basis for compiling mine engineering schedule plan of the open pit,which is the most important work in mining design.Taking Heishan open pit of Xinjiang Houxia coalfield as an example,this paper established the stope model of the first mining area,determined the coal and rock amount in various engineering positions and drew the V-P curve by using Minex 6.0 software,which provided an important basis for mining designers to compile the mining schedule plan and select equipment and mining technology.
