Filling and mining method for increasing yield of mineral exploration

Abstract

The invention discloses a filling mining method capable of increasing the output of mineral mining. An extremely thick ore body with an average thickness of 45m is selected, the long axis of the mine house is arranged vertically, the stope is vertically arranged for the ore body, and is divided into a mine house and an ore pillar. The length of the mine room is the thickness of the ore body; excavate the upper and lower walls along the vein stage outside the vein and excavate the transport roadway and the vein-piercing roadway, and excavate the vein-piercing roadway at the footwall of the ore body to access the ore body, and excavate the horizontal pullway above the vein through the vein-piercing approach. Bottom roadway, a ventilating patio is arranged in the middle of the mine, shallow holes are used to collapse the ore, and the mining layer height is 3.3m, and the middle and deep holes are drilled upwards for one collapse of the mine. The roadway is loaded and transported to the main chute; when the ore is mined, the mine is filled with cement, the roof is connected with mortar and pressure, and the pillar is mined with hydraulic filling. The method improves the ore recovery rate, reduces the ore dilution rate, fully utilizes existing resources, effectively controls ground pressure and surface subsidence, and optimizes the surrounding environment of the mining area.

Description

technical field [0001] The invention relates to a mining method, in particular to a filling mining method capable of increasing the output of mineral mining. Background technique [0002] Minerals generally refer to all natural mineral or rock resources that are buried underground (or distributed on the surface, or weathered, or deposited) and available for human use. Mining is one of the ancient fields where human beings engage in productive labor. The development of the mining industry and the expansion of the development and utilization of mineral resources have produced a huge and irreplaceable role in promoting the development and progress of human social civilization. The ancestors of the Chinese nation, like many nations in the world, have been engaged in mineral development and utilization since their birth. Historians divide human history into the Paleolithic Age, Neolithic Age, Bronze Age, and Iron Age, all of which are characterized by the main types of minerals...
