Problems solved by technology

[0002] There is a huge amount of infrastructure construction in cities and towns, and rock blasting operations are required during the construction process. Since some blasting points are relatively close to buildings, conventional blasting methods are not only complicated in construction technology, difficult to implement, and inconvenient to operate, but also produce severe vibrations. And accompanied by flying stones, the operation safety is low, and it will generate noise and affect the environment
In the prior art, there is a method of using an expansion agent to break rocks, but the method has a low operating rate and poor environmental adaptability

Embodiment 1

[0029] 1) Arrange the free surface on the rock, and then drill the broken hole on the free surface of the rock, wherein the height of the free surface of the rock is greater than or equal to the depth of the broken hole, the broken holes are in a row, and each row of broken holes is more than two, broken The diameter of the hole is d, d=38mm, the depth of the broken hole is 16d (608mm), and the distance between two adjacent broken holes is 5d (190mm);

[0030] 2) Fill the broken hole with hot gas generator and sandy clay sequentially from the bottom of the hole, and lock the opening of the broken hole with expansion bolts to seal the opening. The filling height of the hot gas generating agent is 0.4 times (243.2mm) of the depth of the broken hole, and the depth of the expansion bolt inserted into the broken hole is 50mm, and the space between the hot gas generating agent and the expansion bolt is filled with sandy clay. In addition, the tightening torque of the expansion bolt ...

Abstract

The invention discloses a thermal energy rock cleavage crushing method. The crushing method specifically comprises the following steps: 1) a free surface is arranged on a rock; and then, crushing holes are drilled in the free surface of the rock; 2) hot gas generating agents and clay are filled in the crushing holes from the bottoms of the holes in sequence; and openings of the crushing holes are locked by expansion bolts for blockage; and 3) an ignition device is electrified to ingite the hot gas generating agents; the hot gas generating agents are heated to decompose to generate high-temperature gas; and the high-temperature gas expands in the closed crushing holes to crush the rock. The crushing method has the advantages of: (1) no vibration harm, no generation of flying stones and no environmental influence by noise; (2) simple construction process, convenience for operation and high operation safety; and (3) high environmental adaptability and great improvement of the operation efficiency compared with a crushing method using an expanding agent.

Description

technical field [0001] The invention relates to the field of rock crushing, in particular to a thermal energy rock splitting and crushing method. Background technique [0002] There is a huge amount of infrastructure construction in cities and towns, and rock blasting operations are required during the construction process. Since some blasting points are relatively close to buildings, conventional blasting methods are not only complicated in construction technology, difficult to implement, and inconvenient to operate, but also produce severe vibrations. And accompanied by flying stones, the operation safety is low, and it will generate noise and affect the environment. And the method that adopts expansive agent to break rock has appeared in the prior art, but this method operation rate is low, and environmental adaptability is poor. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the object of the present invention is to provide a t...
