Embodiment Construction

[0017] The present invention will be further elaborated in combination with specific embodiments.

[0018] A cave mining method for facing granite, the steps of which are as follows:

[0019] 1) Reference figure 1 Firstly, a drilling mechanism with a diameter of 3.2 cm is used to open several small holes 10 along a regular quadrilateral path on the side wall of the rock main body 1, because the drilling mechanism will cause errors during the rock drilling process, so that the obtained small holes 10 The actual diameter is between 3.2-3.4cm (such as 3.3cm), the hole distance of adjacent small holes 10 is set to be 4.5-4.7cm (such as 4.6cm), the hole depth is 1.3m, and the upper and lower two of the regular quadrilateral path The distance between horizontal sides is within 75cm.

[0020] 2) Refer to figure 2 with image 3 , every other small hole 10 is reamed with a reamer bit 3, the front portion of the reamer bit is a guide cylinder 30 with a diameter of 3.2cm, which can ...

Abstract

The invention discloses a cave mining method for granite used for a veneer. The method comprises the following steps that 1 multiple holes are formed in the side wall of a rock main body at intervals along a closed path through a punching mechanism; 2 a reamer bit is used to conduct chambering to every other hole, each large hole obtained by chambering are communicated with two adjacent small holes, and a continuous and closed fractured frame is formed at the periphery of a rough stone block to be mined; 3 the inner side of the rough stone block is made to be disconnected with the rock main body by the method of mechanical splitting, then the fractured tough stone block is pulled out, and the required stone materials are obtained. The cave mining method has the advantages that plants are not damaged, the yield is high and the like.

Description

technical field [0001] The invention relates to a stone mining method, in particular to a cave mining method of granite for facing. Background technique [0002] Open-pit mining is a relatively common mining method in traditional stone mining. Open-pit mining is a process of removing the covering of the rock surface to obtain the required stone, mainly including perforation, blasting, sawing mining, transportation and soil discharge, etc. process. 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 large potential 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 ...
