Optimization of raw coal crushing station relocation plan in Hesigewula South Open-pit Coal Mine
In order to reduce the transportation cost of raw coal and achieve the goal of cost reduction and efficiency improvement,a mathematical model for optimizing the relocation step distance of the raw coal crushing station was established using the relocation cost compensation method and the unit cost minimization method.Combined with the current layout and mining planning of the raw coal production system and production and operation indicators of Hesigewula South Open-pit Mine,the relocation step distance and location of the raw coal crushing station were optimized.The relocation step distance of the raw coal crushing station was determined to be 722-795 m,and the relocation period of the crushing station was 5 years.The first level raw coal crushing station of the power plant coal transportation system is located at+872 m level on the west side of the stope,and the raw coal crushing station of No.1 coal production system is moved to+812 m level on the east side of the stope.
