Cross Exploitation And Inner Dumping Scheme Research Of Yilan Open-pit Mine

Mining procedure is the development mode which is mining and stripping engineering on time and spatial in the open-pit mine limit. According to open-pit mine situation and market demand and so on, how to make reasonable of mining technology scheme, in order to improve production efficiency of the mine enterprise, improve economic benefit, which is one of the most important subject in open-pit mineThis paper in view of mining situation of YiLan open-pit mine, put forward mining procedure which turn into cross exploitation and inner dumping from vertical mining. And determined 45°as final stable slope angel. Based on the software system of geological model-mine planning, defined reasonable mining limit and calculate out coal quantities and stripping quantities of YiLan open-pit mine. By compared multi scheme obtain detailed coal and rock qualities table, automatic generating curve of V=f(P), and then decide the east part as the first mining area. By applying simulation technology and ensuring mining-striping project, proposed transitional mode of turning into cross exploitation and inner dumping from vertical mining. That solved project position in transition period and program of yield splicing. According to mining engineering volume in transition period to make detailed inner pumping plan.This thesis research results apply in YiLan open-pit mine getting a good economic benefits.
