A stope shared ventilation and drainage shaft structure

Abstract

The invention discloses a common ventilation and drainage tunnel structure for a stope, which relates to the technical field of underground mining. There are several segmented air inlet tunnels distributed parallel to each other, one end of which is provided with an extended and widened section, and the air inlet patio runs through and communicates with each extension. Widened section, extended The widened section includes the widened section and the extended section, and the water guide dam is located in the widened section; the air inlet and drainage roadways are arranged in parallel on one side of the segmented air inlet roadway, one end of which is directly connected with one end of the air inlet patio, and the other end is set The main drainage roadway; both ends of the air guide roadway are respectively connected to the sides of the air inlet and drainage roadway and the air inlet patio; the half wall is set in the air inlet and drainage roadway. This design can not only stabilize the wind in the stope, but also discharge water normally without generating water mist.

Description

technical field [0001] The invention relates to the technical field of underground mining, in particular to a mine shared ventilation and drainage shaft structure. Background technique [0002] For mines using underground mining, in order to ensure the continuous safe production of mines, a series of tunnels need to be excavated from the surface to the underground to form a system of lifting, transportation, ventilation, power supply, air supply, water supply, drainage, communication, etc. The quality of stope ventilation and timely removal of stope water are important contents of mine safety production management. [0003] Taking the segmented caving mining method without pillars as an example, after the development plan is determined, according to the occurrence conditions of the ore body, the stage is divided into several segments according to a certain segment height, and each segment is arranged at a certain interval In the mining roadway perpendicular to ore body tren...

AI Technical Summary

Problems solved by technology

Since the air inlet patio is used not only for stope ventilation, but also for stope drainage, ventilation and drainage interfere with each other, especially when the water inflow in the stope is large, the upper section drainage passes through the lower section roadway and the air inlet drainage The roadway will form a water curtain and bring out a strong wind flow, thereby preventing the upward flow of the wind flow or even changing the direction of the wind flow, thereby reducing the ventilation efficiency of the mine and affecting the stability of the ventilation system
