The programmable controller is interactively connected with an electromagnetic wave generator and a memory. The programmable controller is connected with a transmission circuit and a reception circuit. The transmission circuit transmits electromagnetic pulse signals generated by the electromagnetic wave generator through a transmission antenna, and reflection wave signals of the electromagnetic pulse signals are received by a reception antenna and transmitted to the programmable controller by the reception circuit. An output end of the programmable controller is in communication with a computer in a ground control center. According to the utility model, the geology acquisition and monitoring device is simple and quick in operation, the acquired data is relatively accurate, and the device can meet the requirements of special environment of coal mines; and the acquisition and monitoring of geological conditions during the coal mining are realized, the safety of the coal mining is improved, the time is saved, and the production efficiency is improved.
Description
Technical field
The utility model relates to the colliery technical field, be specifically related to a kind of for process of coal mining to situations such as geological condition such as gushing water, gas is outstanding gather, device for monitoring.
Background technology
In China, coal is the main energy, and can the colliery keep the safety in production and directly have influence on development and national economy.In the engineering of Coal Production and tunnel excavation, run into complicated geologic anomaly situation through regular meeting, if fail to detect the clear accidents such as landslide, gushing water and gas is outstanding that tend to cause in advance, cause serious economy loss and safety problem.Especially the developed recently caving coal technology of getting up, the tectonic structure of its design, construction and coal seam and country rock, remaining coal thickness, bottom coal thickness etc. have close relationship.Methods such as DC electrical method, Electromgnetically-transparent, slot wave earthquake have successively appearred in the development that decades have been experienced in physical prospecting in the coal mine and exploration, and these methods have all obtained certain achievement in application in practice.Surveying in the well is a kind of special Exploration Domain, and at first subsurface environment is abominable, except the space condition restriction that is subjected to the tunnel, also will be subjected to the infringement of moisture, dust and Device in Gas; Secondly in well physical prospecting be a kind of closely, little structural exploration, so the equipment of physical prospecting in the well and method must have characteristics such as easy to use, high precision.Factors such as the inconvenience that Detection Techniques are used just because of detecting devices in the well and precision be low in the past, restricting their application under mine: simultaneously, these methods can not effectively be surveyed the thickness of remaining coal in the caving recovery process.At present, in the coal mining field, press for the detecting devices of limited condition of work under the suitable coal mine of little, in light weight, the simple to operate quick order of a kind of volume.
The utility model content
The utility model will solve above-mentioned deficiency exactly, provide a kind of for process of coal mining to geological condition gather, monitoring device.
In order to reach above-mentioned effect, the utility model provides a kind of and gathers monitoring device for coal mining geology, comprises Programmable Logic Controller, and described Programmable Logic Controller is connected with electromagnetic wave generator, storer interactive mode respectively; Programmable Logic Controller is connected with radiating circuit and receiving circuit, and described radiating circuit sends the electromagnetic pulse signal that electromagnetic wave generator produces by emitting antenna, and its reflection wave signal receives through receiving antenna, and is transferred to Programmable Logic Controller by receiving circuit; The output terminal of described Programmable Logic Controller is by the computing machine communication of wireless transport module and aboveground control center.
