Radio Wave Perspective Applied Under Mine

Abstract

The invention discloses a radio wave penetration instrument under a mine and relates to the mining geological exploration field. The instrument includes an emitter, a receiver, an emission antenna, areception antenna and a processing system. The emitter and the receiver are both connected with a lift mechanism. The lift mechanism includes a cylinder body and a piston in sliding fit with the innerwall of the cylinder wall. A connecting rod extending out of the cylinder body is connected under the piston. One end, extending out of the cylinder body, of the connecting rod is connected with theemitter and the receiver. The cylinder body is divided by the piston into a storage chamber and a detection chamber. A gas detector is arranged in the detection chamber. The storage chamber is communicated with a sucker. The connecting position of the storage chamber and the sucker is provided with a solenoid valve. The solenoid valve and the gas detector are connected with a controller through signals. The invention solves the problem that a conventional radio wave penetration instrument cannot change in position vertically to carry out comprehensive detection of a working face. The inventionmainly provides the radio wave penetration instrument that carries out penetrating detection on tunnels under a mine transversely and vertically.

Description

Technical field [0001] The invention relates to the field of mining geological detection, in particular to a radio wave perspective instrument used in mines. Background technique [0002] In the mining process of coal seams or mineral deposits, the working space where coal or minerals are directly mined is generally called the stope or stope for short. In the process of coal mining or ore deposit mining face, geological abnormalities such as faults, coal seam thinning areas, collapsed columns, water-rich areas, etc., affect the mining progress and safety of the mining face. Usually, the mining face needs to be pitted before the mining. Through detection, to find out the occurrence of abnormal geological bodies in the mining face. [0003] At present, the most commonly used method for pit penetration detection is radio wave perspective. The principle is that when radio waves are used as the propagation medium to propagate in the coal seam of the working face, when encountering faul...
