A Mining Method of Partition Combined Filling

Abstract

The invention discloses a partition combined filling mining method, step 1: arranging the stope: the stope is divided into left and right stope along the direction of the ore body, and one front and one back; the stope is divided into three sections along the vertical direction, each The section is divided into three layers; Step 2: Construction of the vertical ore body through the vein exploration roadway to the bottom column, construction of the stope boundary construction measure inclined shaft to the top of the bottom column, and construction of the bottom level roadway along the direction of the ore body near the position of the bottom column near the inclined shaft of the measure , and then fill the return air shaft in the stope near the lower wall, and connect with the upper two sections; Step 3: Slip the mine shaft and pedestrian drainage shaft from the vein-piercing exploration roadway to the outside of the construction vein; use the bottom level roadway as a free On the surface of the stope, carry out one-time sheet pressing and second sheet-pressing mining respectively upwards in the two partitioned stope layers, and then recover layer by layer; after the mining is completed, set up a pedestrian drainage well, lay an artificial false bottom, and fill and pull the bottom layer; the structure of the invention is simple , Reasonable structure, high mining efficiency, two adjacent stopes can be merged and connected for joint mining.

Description

technical field [0001] The invention relates to the technical field of underground mine mining engineering, and in particular relates to a filling mining method, which is particularly suitable for the safe and efficient recovery of the subregional combined filling mining method of ore with average ore value and thin to medium-thick inclined ore bodies. Background technique [0002] With the tightening of national safety and environmental protection policies, more and more mines use the filling and filling mining method in underground mining. In the mining of average ore value, thin to medium-thick inclined ore bodies, the layered filling method is the most commonly used method. This method needs to reserve a bottom column, and each stope must set up a mining and cutting project, including out-of-vein Compared with other mining methods such as approach method, staged deep hole and subsequent filling method, for projects such as pedestrian water filter wells, filling ventilati...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems of large overall mining and cutting engineering volume, low recovery rate, low mechanization degree and low mechanical utilization rate faced by the layered filling mining method in the mining of thin to medium-thick ore bodies in underground mines, the present invention provides a simple structure. , Reasonable structure, high mining efficiency, large production capacity, high recovery rate, small amount of mining engineering, can combine two adjacent stopes to connect and mine the sub-area combined filling mining method
