Mining method for ore bed

Abstract

The invention belongs to the field of mineral mining, in particular to a mining method for an ore bed. The mining method comprises the following steps of: mining in a large-section tunneling way; during mining, building annular bodies with upper, lower, left and right faces on four walls of a mined vacant mining area by using reinforced concrete structures; building a section of annular body once a section is mined forward; building an integrated structure by using two adjacent annular bodies; building vertical beams for supporting at intervals between the upper and lower inner walls of the annular bodies; performing anti-permeation and anti-leakage treatment on the inner wall faces of the annular bodies; and forming a mine cave after the ore bed is mined completely. The method has the advantages that: during mining, the annular bodies with reinforced concrete structures which are subjected to anti-permeation and anti-leakage treatment are built on the four walls of the mined vacant mining area, and the operating space under the ore bed is large, so that modern large-scale operation can be realized; and the danger coefficient of mining worker operation is lowered, the mine cave can be reused after mining is completed, the comprehensive mining cost is low, waste of resources is not caused, and the method is suitable for mining various minerals.

Description

technical field [0001] The invention belongs to the field of mineral mining, in particular to a method for mining a mineral seam. Background technique [0002] At present, the mining of ore deposits generally needs to build a series of roadways to access the ore body, so that the ground and underground form a complete system of lifting, transportation, ventilation, drainage and power supply, so as to send personnel, materials, equipment, power and fresh air to the mine. People go underground, and at the same time send ore, waste rock, mine water, dirty air, etc. to the ground. This method has a small mining space, some large-scale machinery cannot enter the mining area, and the minerals in the mine cannot be completely collected. Safety accidents, the safety of mining workers cannot be guaranteed, and backfilling is required after mineral mining is completed to prevent landslides. Contents of the invention [0003] The object of the present invention is to provide a miner...
