Embodiment 1

[0019] Such as figure 1 As shown, for the mines in arid areas such as Dunhuang jade and tremolite in Guazhou County, Gansu Province, the drilling and injection method is used to simultaneously carry out the block mining of injection polymerization and high-pressure expansion cracking. The process steps are as follows:

[0020] 1. The process of drilling and grooving is to use a rock drill and a 40mm drill bit to mine cuboid blocks on three mutually perpendicular cracking surfaces, and drill them in a straight line with a distance of 20-100cm and deep holes of 100-300cm. Three rows of deep holes, and then use the groove tool (Hubei Building Materials Research Institute Luo Zuchun) to make grooves with a sharp angle of 60 degrees and a depth of 8mm, so that the deep holes become approximately diamond-shaped and increase the compression area;

[0021] 2. The process of setting the glue injection nozzle is to use 3 high-pressure glue injection devices (Beijing Lioud Crack Treatmen...

Embodiment 2

[0027] For granite and serpentinized marble, cuboid stones used for carving columns and Buddha statues. The process steps for strong penetration and strengthening are:

[0028] 1. The drilling process is to use a thin-walled drill to drill a deep hole with a diameter of 80 mm and a depth smaller than the length of the material body along the center of the length direction;

[0029] 2. The process of setting the glue injection nozzle is to pre-embed the glue injection nozzle in the orifice with structural glue for stone, and use a high-pressure rubber hose to communicate with a high-pressure glue injection device;

[0030]3. The polymer glue preparation process is to use Yabang 7936 unsaturated resin, OT curing agent, KH570 silane coupling agent and styrene in a mass ratio of 100:2:2:80 to form a single-component glue with a viscosity of 100cps. liquid;

[0031] 4. The surface filling process is to fill the gaps on the surface of the stone with a width of more than 0.1mm with...

Embodiment 3

[0035] For minerals with obvious cracks such as stromatolites, quartzites, and tremolites, the process of expanding and cracking along the cracks is as follows:

[0036] 1. The drilling and grooving process is to drill holes with a distance of 80cm along the vertical plane of the cracks in the ore body with a width of more than 0.5mm and a sharp angle of 50° for two rows of deep holes arranged vertically. And the groove with a depth of 10mm makes the round hole form an approximate diamond shape, and the deep hole and the sharp corner of the groove are arranged in a straight line;

[0037] 2. The process of setting the injection nozzle is to configure the injection nozzle with a valve and a funnel, insert a 500W resistance wire heating device into each deep hole, use two insulated wires to lead out along the gap between the nozzle and the round hole, and use structural glue sticky;

[0038] 3. The polymer glue configuration process is to use methyl methacrylate, organic peroxi...

Abstract

The invention belongs to the field of stone materials and mining, and particularly relates to a punching injection type fractured stone material mining and processing method. The method mainly solves the problems that minerals such as siliceous jades, amphiboles, granites, quartz stones, stromatolites, serpentine-jades, marbles and the like are difficult to mine and have low yield. The technical scheme is that a macromolecule glue solution and an injection device are adopted, deep holes are used for high-pressure injection, the stone material is spalled under the high pressure of 20-100 MPa, and adhersion bonding healing and injection spalling of joint fissure rocks are achieved through a drilling and grooving process, a rubber nozzle arranging process, a macromolecule glue solution configuration process, a surface joint filling process, a high-pressure injection process and a surface glue permeation process. The method has the advantages that mining can be performed easily, and the yield is high.

Description

technical field [0001] The invention belongs to the field of stone material and mining thereof, and in particular relates to a drilling and glue injection method for mining and processing cracked stone material. Background technique [0002] At present, in the field of stone and its mining, the mining of non-metallic minerals such as marble, granite and sandstone has gradually shifted from drilling holes and blasting with explosives to drilling holes and using expansion agent static blasting. In order to further improve the wasteland rate of mining, the mining methods of circular saws and beaded wire saws are gradually promoted. However, in the case that there are many cracks in the rock mass of the mine, no matter what method is used for mining, the reality that the waste rate is less than 30% will inevitably form a problem of a large amount of gravel accumulation. How to effectively utilize stone materials for architectural decoration, especially how to utilize more silic...
