Inclined roadway mine transient electromagnetic interference-free transmitting device and using method thereof

Abstract

The invention discloses an inclined roadway mine transient electromagnetic interference-free transmitting device and a using method thereof. The device comprises a transient electromagnetic transmitting wire frame, a transmitting wire frame at the top of the transmitting frame and a transient electromagnetic instrument connected with the transmitting wire frame. The device is made of wood materials with good insulation and magnetism insulation, the whole structure is connected through mortise and tenon structures and bolts, no ferromagnetic materials exist, the frame body structure is stable,insulating paint is sprayed to an outer surface of the device, and waterproof, explosion-proof, insulating and anti-interference effects are achieved. By controlling the device, the device can adapt to a fluctuating slope of the roadway and adapt to the distance change between the transmitting wire frame and a top plate, the bottom plate or the head-on position of the roadway, the device can moveon a roadway track, and omni-directional electromagnetic signal transmitting and receiving of the transmitting wire frame are achieved. When a transient electromagnetic instrument system works, the transmitting device is free of human assistance and is not affected by electromagnetic interference of a human body and the support, and multifunctional control over the mine transient electromagnetic transmitting device is achieved.

Description

technical field [0001] The invention relates to a non-interference transient electromagnetic emission device for mines in inclined tunnels and a method for using the same, in particular to a non-interference, omnidirectional, and stable frame-based emission device and control method for transient electromagnetic fields suitable for complex tunnel terrain. The utility model belongs to the field of mine transient electromagnetic method measurement. Background technique [0002] At present, the transient electromagnetic method detection technology has been widely used in coal mines in my country. The commonly used transmitting device is that the transmitting coil is wound on the launching rod, and the height and direction of the transmitting wire frame are controlled by a single person or two people. This control method It will bring a series of problems, such as large randomness, inaccurate launch frame height, too large deviation of launch direction or direction angle, unstabl...

AI Technical Summary

Problems solved by technology

However, due to the particularity of underground work and the complexity of the roadway, it is often difficult to take into account the stability of the launcher body, the adaptability to changes in the height and slope of the roadway, the detection direction, the launch angle and The accuracy of the side length change of the transmitting frame, the influence of the electromagnetic induction field generated by the human body and the material of the transmitting device itself on the received data due to the excitation of the primary field

In summary, there is a lack of a package solution that can completely solve the above problems
