Embodiment Construction
[0035] Further detailed explanation through specific implementation mode below:
[0036] The reference signs in the drawings of the description include: transmitter 1, limit block 2, cylinder body 3, piston 4, connecting rod 5, storage room 6, detection room 7, gas detector 8, suction cup 9, solenoid valve 10, Roadway roof 11.
[0037] like figure 1 As shown, the present invention is applied to the radio wave perspective instrument under the mine, including a transmitter 1, a receiver, a transmitting antenna, a receiving antenna and a processing system connected with the receiver signal, the transmitter 1 sends radio waves through the transmitting antenna, and the receiver The radio wave signal is received by the receiving antenna and passed on to the processing system;
[0038] Both the transmitter 1 and the receiver are connected with a lifting mechanism (the connection between the receiver and the lifting structure is not shown), the lifting mechanism includes a cylinder ...

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 mine geological detection, in particular to a radio wave see-through instrument used in mines. Background technique [0002] In the mining process of coal seams or ore deposits, the working space where coal or minerals are directly mined is generally called the mining face or stope for short. During the mining process of coal mine or ore deposit mining face, geological anomalies such as faults, coal seam thinning areas, subsidence columns, and water-rich areas affect the mining progress and safe production of the mining face. Usually, the mining face needs to be excavated before mining. Through detection, to find out the occurrence of geological anomalies in the mining face. [0003] At present, the most commonly used method for pit penetration detection is the radio wave perspective method. The principle is that when radio waves propagate in the coal seam of the working face as the propagation medium, when encoun...
