High-energy storage positioning and orienting active-excitation seismic source gun and using method

Abstract

The invention discloses a high-energy storage positioning and orienting active-excitation seismic source gun and a using method, which is applied to mine seismic exploration. The high-energy storage positioning and orienting active-excitation seismic source gun comprises a sliding fixing support and a gun body arranged on the sliding fixing support, wherein the sliding fixing support comprises a bushing fixed clip holder and three sliding fixing support legs arranged at the bottom of the bushing fixed clip holder; and the gun body comprises a gun barrel and a winch device. In the case of use, the high-energy storage positioning and orienting active-excitation seismic source gun body is firstly fixed, the winch is rotated, a winch drum is driven to rotate to enable a tensile steel wire rope to be tightly pulled, an anti-impact steel bar is driven and pulled to slide, and a high-pressure bearing spring is contracted and deformed. In the case of use, a safety brake lock is triggered, the high-pressure bearing spring pushes the anti-impact steel bar to be impacted on a target object instantly after being separated from the high-pressure bearing spring in an unconstrained state, and a seismic source is generated. The high-energy storage positioning and orienting active-excitation seismic source gun has the advantages of low cost, easy maintenance, simple structure, light and convenient carrying, economy and reliability, and simple operation, considers both handheld and fixed operation, has continuous adjustable characteristics of shaking effects, and is applied to a seismic exploration project in various solid media.

Description

technical field [0001] The invention relates to an active excitation seismic source gun and a use method thereof, in particular to a high-energy-storage positioning and directional active excitation seismic source gun and a use method for mine seismic exploration. Background technique [0002] Mine geodynamic disasters, mainly rock burst, coal and gas outburst, and water inrush, have become the main problems in the safety field of my country's coal industry. As an induced disaster in the process of mining production activities and engineering construction activities in underground coal mines, the frequency and scope of dynamic disaster accidents are increasing with the increase of mining depth year by year. [0003] For such disasters, conventional mine dynamic monitoring methods and technologies can no longer meet the safety needs of disaster early warning in mining and production activities. A number of technical means based on the application of geophysical principles an...

Problems solved by technology

[0006] When the hammer is used as the source of the shock, the hammer head accelerates down and hits the hammer pad, and the energy is transferred to the coal rock mass through the hammer pad; when the explosive is used as the source of the shock, the high-temperature and high-pressure gas generated by the explosion of the explosive expands rapidly to form an instantaneous pulse force, and acts In the coal and rock mass, vibration waves are generated; this type of active vibration source excitation operation has the technical problems of high labor intensity of manual hammering, weak active vibration effect, high risk of blasting shock, and unfavorable control of surrounding rock stability, which seriously affects the mine.
