Embodiment Construction

[0032] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the required protection scope is not limited to the description;

[0033] Example: When filling and mining the middle section of Qingcaichong Mine 820 in the central part of Guizhou, the inclination angle of the ore body is only about 35°, which cannot make the ore after blasting self-slip under the action of gravity, resulting in a large loss of ore, and must be exposed to the whole Anchor nets and cable supports are carried out in an empty field, resulting in high support costs and low work efficiency.

[0034] Now adopt the gently inclined ore body self-slip mining method provided by the invention to carry out filling and mining of the ore body. First divide the ore body: divide the ore body into several panels along the ore body trend, each panel is evenly divided into several mine houses, and divide the mine houses into ...

Abstract

The invention discloses a self-slippage mining method of a gentle dip ore body. The method comprises the steps of ore body dividing-accurate mining-cutting slot constructing-cutting slot supporting-bottom removing-brushing and recovering-mine discharging-filling, etc. according to the method, only the cutting slot is supported by an anchor cable net, so that the mining cost can be greatly reduced; the cutting slot is supported by the anchor cable net, and an anchor cable is connected by a flexible steel belt, so that a top plate is a suspended whole body, the stability can be improved, and the safe recovery can be realized; ore bodies at two sides of the cutting slot are exploded in a brushing way, so that compared with the existing single-side retroactive mining method, the method shortens the recovery time by a half, the efficiency can be greatly improved, the stope exposure time can be reduced, and the safety can be improved; according to the bottom removing construction, the self-slippage degree of the ore can be enlarged, and the recovery efficiency can be improved.

Description

technical field [0001] The invention relates to a filling mining method, in particular to a self-sliding mining method suitable for a gently inclined ore body with a small inclination angle of the ore body and incapable of self-slipping of the ore. Background technique [0002] The filling mining method is a commonly used mining method for mineral resources at present, and the filling mining method belongs to the artificial support mining method. In the mine room or ore block, as the mining face advances, the filling material is sent to the goaf to manage the ground pressure, control the collapse of the surrounding rock and the movement of the ground surface, and protect the formed filling body down for recovery. Filling mining methods are divided into single-layer filling method, upward layered filling method, downward layered filling method and segmented filling method. When mining difficult-to-mining ore bodies such as gently inclined thin ore bodies, the single-layer f...
