Coal and rock mass conductive fracturing device based on liquid carbon dioxide

Abstract

The invention discloses a coal and rock mass conductive fracturing device based on liquid carbon dioxide. The coal and rock mass conductive fracturing device comprises a storage tank body, a filling head is connected to the upper end of the storage tank body in a threaded mode, an energy release mechanism is connected to the lower end of the storage tank body in a threaded mode, a shearing sheet is arranged at the bottom end of the inner part of the storage tank body, sealing pads are correspondingly arranged on the upper surfaces and the lower surfaces of the sealing pads, an air inflation hole is formed in the filling head, a remote control mechanism is fixedly installed on the upper surface of the filling head, an activator is connected to the lower surface of the filling head in a threaded mode, and an electric heating pipe is arranged in the activator. According to the coal and rock mass conductive fracturing device, the remote control mechanism is arranged, a power supply can beremotely controlled to supply power for the electric heating pipe, thus detonation is remotely triggered, the operation is simple, and disassembly and installation are convenient; a second energy release head is rotatably installed on a first energy release head. The direction of energy release can be adjusted, the accuracy of blasting can be improved, an adjusting port capable of adjusting an angle is arranged, and thus horizontal exhaust of the device is avoided.

Description

technical field [0001] The invention relates to the technical field of blasting devices, in particular to a coal and rock mass conduction cracking device based on liquid carbon dioxide. Background technique [0002] The carbon dioxide cracker uses liquid carbon dioxide to heat and gasify and expand, and quickly releases high-pressure gas to break rocks or fall coal. It solves the defects of explosive blasting mining in the past, large destructive and high-risk ore body crushing in pre-cracking, and contributes to mine safety. It provides reliable guarantee for mining and pre-splitting, and is generally applicable to operations in coal mines and non-coal mines. [0003] However, the traditional carbon dioxide cracker triggers blasting by connecting wires, which is cumbersome and unstable; after installation, the carbon dioxide cracker may cause inaccurate blasting due to some errors, and the traditional carbon dioxide cracker cannot adjust the direction of the energy release ...
