Embodiment Construction

[0041] The technical solutions of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0042]The fracturing device and method provided in the present disclosure can be used for expansion, cracking, and decomposition mining of ore bodies or ore substrates. It should be noted that rock-based hard and brittle materials have the obvious characteristic that the tensile strength is much smaller than the compressive strength. In view of this , the cracking device and method provided by the present disclosure is to overcome the tensile strength of the ore in the process of expanding and cracking the ore, so the difficulty of decomposition is greatly reduced, and the mining efficiency is improved accordingly.

[0043] Such as figure 1 In one embodiment shown, the cracking device provided by the present disclosure includes a casing 1 , a switch valve 2 , an air inlet 31 , and a control air passage 32 . In this embodiment...

Abstract

The invention relates to ore extraction and specifically provides a cracking device and an ore extraction method. The cracking device comprises a shell, a switch valve, an air inlet channel and a control air channel, wherein a chamber is formed in the shell; an air vent which is connected with the chamber is formed on the shell; the switch valve is arranged in the chamber and is in sliding fit with the chamber; the opening / closing of the air vent is controlled by the sliding of the switch valve in the chamber; the chamber is divided into an air storage chamber and a control chamber by the switch valve; the air inlet channel is connected with the air storage chamber and is used for filling air into the air storage chamber; the control air channel is connected with the control chamber and isused for filling air into the control chamber; the switch valve is capable of sliding under the effect of air pressure difference of the air storage chamber and the control chamber so as to control the air vent to open or close. The cracking device provided by the invention has a simple structure, is safe for operation and is capable of quickly opening the valve, so that the extraction efficiencyof stone materials is higher.

Description

technical field [0001] The disclosure relates to stone mining, in particular to a cracking device and an ore mining method. Background technique [0002] At present, the mining of ore mainly includes two methods: explosive mining and non-explosive mining. Among them, explosive mining refers to the mining of stone through the blasting of explosives installed in boreholes. The method of blasting mining produces a lot of dust and noise pollution, and causes great damage to the mountain body of the mine, which leads to the fragmentation of stone in the ore body and reduces the mining rate. Therefore, the mining of stone by blasting mining method has been basically prohibited at present. Non-explosive mining includes mechanical cutting or bursting mining. Mechanical cutting refers to the use of flame cutting or wire saw to cut and mine stone ore bodies. This method requires high equipment and site, low mining efficiency, and cannot cope with large-scale mining. Task. [0003] B...
