Environment-friendly mine hole exploitation method

Abstract

The invention discloses an environment-friendly mine hole exploitation method. The environment-friendly mine hole exploitation method comprises the following steps that a working plane is selected, and at least four symmetrical holes are formed in the working plane; a water jet cutting gun nozzle stretches into one of the predrilled holes and faces towards another hole, and a water jet cutting gun moves from inside to outside till a plane is cut; a spalling device is put into the holes and conducts spalling on cut stone so that the bottom surface of the stone can be fractured from a mine body; and the fractured stone is taken out. The environment-friendly mine hole exploitation method has the beneficial effects that massive rock exploitation is achieved mainly through water jet and waterpower in the operating process, the whole process is free of flying dust and low in noise, and the comfort of the working environment of workers is improved; no vibration is produced in the operating process, and the dangerous situation that persons are injured by collapsing and stone splashing due to explosive blast and vibration of an explosive material exploitation method is avoided; and exploitation of stone with the depth being 2 m or above can be achieved through the environment-friendly mine hole exploitation method, the stone yield is high, and operation is simple.

Description

technical field [0001] The invention relates to the technical field of stone mining, in particular to an environment-friendly mine cave mining method. Background technique [0002] Traditional stone exploitation adopts explosive blasting method or open-pit mining. As we all know, mining by explosive blasting has disadvantages such as poor safety performance, irregular ore blocks and low material yield; open-pit mining is a method of removing the rock surface. Covering, the process of obtaining the required stone mainly includes processes such as perforation, blasting, sawing mining, transportation and soil discharge. Surface mining requires the stripping of large layers of soil overlying useful rock surfaces, as well as fractured rock of considerable thickness. As a result, a large amount of mountain land and farmland need to be occupied for spoil. A large amount of vegetation is destroyed, and the green hills are covered with white, and the tailings pool formed also has a...

Problems solved by technology

As a result, a large amount of mountain land and farmland need to be used for spoil

Caused a lot of vegetation damage, the green hills were covered with white, and the tailings pool formed also had a large safety hazard

In the early stage of platform mining, the cost of compensation, the cost of divestiture, and the cost of governance in the later stage are all very huge
