[Abstract]:In this paper, the principles of open-pit mining, mining system engineering, technical economics and computer technology are comprehensively used, and through investigation and research, theoretical analysis and field engineering practice, The capacity of semi-fixed rock crushing station, the selection and layout optimization of crushing station and the elevation adjustment method of belt conveyer are determined under the condition of near horizontal opencast mine. And the economic parameter calculation of semi-continuous system is studied deeply. According to the influence factors and reliability analysis and calculation system capacity two methods are put forward to establish the belt conveyor parameter checking calculation model. The determination of the number of semi-fixed rock crushing stations is studied in detail, and the method of determining the number of semi-fixed rock crushing stations based on the number of unloading stations of trucks is put forward. The calculation model of the optimal position of the rock semi-fixed crushing station in the service block section is established, and the moving mode of the semi-fixed rock crushing station is sorted out. Two methods of unloading the truck along radial and tangential direction towards the rock semi-fixed crushing station are analyzed, and the reference values of the moving time and cost of the semi-fixed rock crushing station in the domestic opencast mine are given according to the actual situation in the domestic open-pit mine. In order to solve the problem of the difference in height between the belt conveyor and the belt conveyor in the working face, the method of lowering the elevation of the belt conveyor and the method of temporary measures are put forward in order to solve the problem of difficulty in lapping. According to the requirement of rock stripping semi-continuous process in near-horizontal open-pit mine and the characteristics of rock semi-fixed crushing station, the semi-continuous economic parameters of rock semi-fixed crushing station are calculated and compared. It is put forward that the economic parameters of semi-fixed rock crushing station should be calculated, analyzed and compared with the single-bucket truck process in the same condition, and the economic effect of semi-continuous process can be determined by calculation, analysis and comparison. The quantitative calculation and comparison model are established for the calculation of the economic parameters of the three processes mentioned above. This paper puts forward the problem of vertical reverse transportation of dump truck in opencast mine, and quantifies the added value of transportation cost of open-pit mine, which provides a more accurate transportation route and transportation cost calculation model for open-pit mine. The application of semi-fixed rock crushing station in Heidaigou opencast coal mine is taken as an example.
