Problems solved by technology

In addition, these methods of operation are inefficient, dangerous, noisy, and costly, making it difficult to meet the requirements of sustainable, low-carbon, and environmentally friendly development. Especially when they are close to towns, each blasting is equivalent to a magnitude 3 earthquake, which seriously interferes people's work, study and life

Embodiment Construction

[0030] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0031] The mining method of the plate-shaped distribution metal ore of the present invention adopts tools, equipment and facilities such as diamond wire saw 2, wire saw machine 3 and track 4, and in the parallel horizontal roadway 1 of different layers excavated in the scope of predetermined operation area, to The ore body is cut and constructed, and finally the ore body is pushed into the roadway with a hydraulic pusher 7 and then pulverized and carried away.

[0032] Such as figure 1 As shown, in the predetermined operation area of ​​the mining area, several parallel horizontal roadways 1 are excavated according to the direction of the plate-shaped distributed metal ore. The horizontal roadway 1 divides the predetermined operation area into two square cutting bodies. Now take the cutting operation of the upper cutting body as an example to ...

Abstract

The present invention provides a mining method for metallic ore distributed like plates, parallel horizontal tunnels are excavated in a predetermined operating region range, the horizontal tunnels are in different levels, in the horizontal tunnels, cutting construction is performed by use of a diamond rope saw, a rope saw machine, a track, a hydraulic pusher and other tools, equipment and facilities, an ore body is cut to form a predetermined mobile gap, finally the ore body is pushed from a horizontal tunnel at one side to another horizontal tunnel at the other side by use of the hydraulic pusher, and then is crushed and carried away, and the purpose of mining of the metallic ore distributed like plates is realized. The invention provides a new, safe, environmentally-friendly, efficient and low-cost mining method for the metallic ore distributed like plates underground.

Description

(1) Technical field: [0001] The invention relates to mining of underground metal ore bodies, in particular to a mining method of plate-shaped distributed metal ore. (2) Background technology: [0002] Metal ores mostly refer to non-ferrous, black and other metal ores. [0003] The mining of metal ore is divided into open-pit mining and underground mining. The prior art usually adopts the mining method of explosive blasting and mechanical crushing to metal ore. The negative effects of these mining methods on mineral resources and the ecological environment mainly include four major sources of harm: resource loss, surface subsidence, discharge of waste rock, and discharge of tailings. Metal ore bodies with plate-like distribution mostly extend for several kilometers within a thickness of about 0.5 meters. In the original metal mining method, a large amount of surrounding rocks of metal ore bodies are also broken together, resulting in a large number of waste rocks and tailing...
