Mine room method in stage of rock drilling with trucks cooperatively out of ore

Abstract

Provided is a truck coordinated mine removal subsection drilling stage room mining method. The method comprises the following steps that a thin vein belt formed by a thick or extremely thick steeply inclined mine body or a steeply inclined parallel extreme thin vein of a solid mine rock is divided into stages, mine blocks are divided in the stages, and the mine blocks are divided into mine rooms and mine columns; a transportation roadway is arranged at the boundary of the mine rock, and a slope ramp is distributed outside the vein; an air pedestrian patio is excavated in a studding, and a section drilling roadway is excavated from the patio; a mine drawing funnel and a short chute well accessible mine body are excavated through the transportation roadway; and a medium length hole mine drawing in an upper fan section is adopted when the mining is conducted, and the mine block is directly put into the track through the short chute well and the mine drawing funnel and then is transported out through the slope ramp. According to the truck coordinated out of mine section drilling stage room mining method, the method improves a traditional subsection drilling stage mine room method, the work amount of mining and cutting is reduced, the degree of mechanization is improved, cooperation of mine extraction and mine removal is ensured, and the production efficiency of the mine is improved.

Description

technical field [0001] The invention relates to a mining method for underground mining of metal mines, in particular to a mining room method in the stages of rock drilling with trucks out of the mine, which is suitable for thick and extremely thick steeply inclined ore bodies with stable ore rocks or sharply inclined parallel extremely thin The mining of veinlets composed of ore veins. Background technique [0002] For thick and extremely thick steeply inclined ore bodies with stable ore rocks or thin vein belts composed of steeply inclined parallel extremely thin veins, vertical deep hole segmented rock drilling stage mine method and horizontal deep hole ore falling stage mine house method are generally adopted for mining , the vertical deep hole segmented rock drilling stage ore mining method has the advantages of high mining intensity, good ventilation conditions, and large production capacity of the mine house. Disadvantages such as large engineering volume and low mini...

AI Technical Summary

Problems solved by technology

[0002] For thick and extremely thick steeply inclined ore bodies with stable ore rocks or thin vein belts composed of steeply inclined parallel extremely thin veins, vertical deep hole segmented rock drilling stage mine method and horizontal deep hole ore falling stage mine house method are generally adopted for mining , the vertical deep hole segmented rock drilling stage ore mining method has the advantages of high mining intensity, good ventilation conditions, and large production capacity of the mine house. Disadvantages such as large amount of engineering and low mining efficiency

In the horizontal deep hole ore falling stage, the ore body is recovered by the mine method, which has the advantages of high labor productivity and low mining cost, but has the disadvantages of certain damage to the bottom structure when the ore collapses.
