specific Embodiment approach 1

[0011] Specific implementation mode one: as Figure 1-2 As shown, the steps of a method of using tailings and gangue to fill the goaf formed after mining in this embodiment are as follows:

[0012] Step 1, transporting the discarded gangue 1 on the ground to the processing plant 2;

[0013] Step 2, put the discarded gangue 1 into the crushing equipment in the processing room 2, and crush the discarded gangue 1 into gangue fragments with a particle size of 0.5 cm to 1 cm through the crushing device;

[0014] Step 3, putting the crushed gangue fragments into a woven bag and sealing the mouth of the woven bag;

[0015] Step 4: Transport the woven bags filled with gangue fragments to the goaf 3 after mining for filling.

specific Embodiment approach 2

[0016] Specific implementation mode two: as Figure 1-2 As shown, the crushing equipment in step 2 of the method for filling the goaf formed after mining with gangue described in this embodiment is a type of SCF600×800, the maximum feed particle size is 360mm, and the minimum discharge particle size is 2mm ore crusher.

specific Embodiment approach 3

[0017] Specific implementation mode three: as Figure 1-2 As shown, the processing plant 2 in step 1 of the method for filling the goaf formed after mining with waste rock in this embodiment is set on the ground.

Abstract

The invention relates to a method for filling a gob formed after mining, in particular to a method for filling a gob formed after mining by using gangue. The method solves the problems of large gangue occupied area, environmental pollution caused by emitted dust and toxic gas and harm and damage caused by gob collapse in conventional mining. The method comprises the following steps of: transporting waste gangue on the ground to a processing plant; 2, putting the waste gangue into crushing equipment in the processing plant, and crushing the gangue into crushed gangue with grain diameter of 0.5 to 1 centimeter through the crushing equipment; 3, filling the crushed gangue into woven bags, and sealing the openings of the woven bags; and 4, transporting the woven bags filled with the crushed gangue to the mined gob, and filling the gob. The method is used for filling the gangue into the gob formed after mining.

Description

technical field [0001] The invention relates to a method for filling the goaf formed after mining, in particular to a method for filling the goaf formed after mining with gangue. Background technique [0002] With the advancement of science and technology and fierce competition among countries, people's demand for resources has grown rapidly, and mineral resources have been continuously mined. After mining, a large amount of gangue is piled up in the open air to form a gangue hill, and the gangue stacked in the open air occupies a large amount of land resources. And it emits a large amount of dust, carbon monoxide, carbon dioxide, sulfur dioxide, hydrogen sulfide and other toxic gases, polluting the surrounding environment. After mining, the mine forms a large area of ​​goaf, and the ground of the goaf often collapses and damages buildings, roads, Bridges, farmland, forests, etc. have caused great harm and damage to people's production and life and the natural ecological env...
