Abstract:

Process selection of surface mine is one of the core tasks of surface mine design and the most important decision in surface mining. Mining technology not only decides the development mode of transport, mining procedure, and the overall layout but also decides investment recovery and economic benefit of surface mine. There are many factors influencing process selection of surface mine, both quantitative factors and qualitative factors. The weight of each factor is different. The Analytic Hierarchy Process may considers qualitative and quantitative factors and the weight of each factor, provides a new solution for the process system selection. This paper mainly establishes the process selection index system of surface mining based on Analytic Hierarchy Process and uses the method of to research the choice of rock stripping process between 4#-9# coal in eastern surface mine. It proves the feasibility of the method through the consistent of Process selection and expert proposal scheme.

Key words: Surface mine, Process, Choice
