Stope structure for upward slicing whole tailing cemented filling method

Abstract

The invention discloses a stope structure for an upward slicing whole tailing cemented filling method. The height of one section (c) is 6-8 m, and each section (c) is divided into an upper slice (c1) and a lower slice (c2). A footwall intra-reef following-reef connection roadway (3) is arranged on one sides of the footwalls of ore bodies of the upper slices (c1), and a hanging wall intra-reef following-reef connection roadway (4) is arranged on one sides of the hanging walls of ore bodies of the lower slices (c2); the footwall intra-reef following-reef connection roadway (3) serves as an ore removal connection roadway for stoping of the upper slices (c1), and the hanging wall intra-reef following-reef connection roadway (4) serves as an ore removal connection roadway for stoping of the lower slices (c2); and a middle section hanging wall main haulage roadway (2) communicates with a middle section footwall main haulage roadway (1) through an ore loading across-reef connection roadway (12), the footwall intra-reef following-reef connection roadway (3) communicates with the middle section footwall main haulage roadway (1) through a stope slicing connection inclined roadway (7), and therefore a complete transportation system is formed. The stope structure is high in production capacity, small in stope preparation project amount, simple in process, low in stope supporting cost and capable of achieving second-step continuous mining.

Description

technical field [0001] The invention relates to a stope structure layout of an upward approach layered filling mining method, which is especially suitable for filling mining in underground mines with unstable rock formations, and can be used for layered full tailings cemented filling mining in underground mines of black and non-ferrous metals. widely used in. Background technique [0002] With the continuous increase of human demand for mineral products, mineral resources become less and less. How to develop and utilize mineral resources rationally, efficiently, economically and safely, reduce the loss of resources, reduce the dilution of ore, and improve the quality of ore are common concerns of mineral resource developers. With the advantages of high recovery rate and low dilution rate, the filling mining method has made a breakthrough in the mining of high-value refractory ore deposits. There have been trackless mechanized cemented filling mining methods, point column fi...
