KBA176 mine explosion-proof optical fiber camera (hereinafter referred to as camera) is used for image capture and transmission in important places in underground mines. It is suitable for underground coal mines that contain explosive gas mixtures such as methane and explosion hazards.
The system consists of 2 units of high efficient PV inverters,one unit of mid-voltage transformer(step up transformer).AC power,DC power, monitoring communications ,and other mobile devices integrated in a mobile house, thereby enhancing the system security as well as relaiblility ,convenient to transport and installation ,improving system efficiency and power output as well.
This product uses computer chips, with software modulation and programming functions, adding 15 adjustable channels. Working in 144MHz ~ 166MHz frequency band, the transmitting power can be adjusted from 0.3W to 1.2W. The sensitivity of receiving is higher. It has the function of anti-interference of mute audio, which makes the communication effect clearer and the working performance more stable, safe and reliable. Handheld station is an extension of mine leakage communication system, which is used by underground mobile personnel.
Application: KL6LM(B) Intrinsically Safe Type Miner's Lamp, this product is a portable lighting tool, mainly suitable for underground lighting, but also for tunnels, high-altitude and field operations.
The mine hydrodynamic automatic dust reduction system is mainly composed of hydrodynamic dust remover, automatic sprinkler dust reduction device, main control box, touch sensor, heat release sensor, equipment start and stop sensor and other equipment. The system is programmable, easy to install, energy saving, consumption reduction and high dust reduction efficiency. It can automatically judge the pedestrian, driving and surrounding environment according to the roadway and environmental dust source, and automatically start and stop the dust remover to realize automatic dust reduction.
The working time of underground coal bunker, water bunker, equipment chamber and other works in the coal mine is short. If the electric fan is used to connect the power and arrange the fan, it is very troublesome, time-consuming and labor-consuming. According to this situation, the company has developed FQ series mine pneumatic press in axial flow local fan, which is suitable for short-distance air supply during coal bunker, water bunker maintenance and roadway excavation.
The FJP series of mine spray dust suppression fans are used for dust removal in belt lanes, wind return lanes, and coal mining faces. The dust remover shall be placed on the top of the belt roadway, return air roadway, the rocker arm or body of the shearer or at the place designated by Party A. the underground high-pressure water pipe shall be inserted at the filter inlet, and the filter outlet shall be connected to the water inlet joint of the dust remover through the high-pressure rubber pipe, and the high-pressure water valve equipment shall be opened for operation.
It is used in coalminesin three-phase neutral ungrounded transmission lines with voltage AC 3300V,50Hz. It canmake local and remote control of three-phase asynchronous motor and concentrated control of coal cutter,scraper conveyor, crusher,reversed loader, pump station and other equipments of comprehensive mechanized coalfaces.
It is suitable for the mine with explosive dangerous gas and coal dust. It can control and protect the start and stop of less than 4 three-phase squirrel cage asynchronous motors in the AC 50 Hz and rated voltage ac1140v (660V), and the phase sequence can be changed when stopping. It is especially suitable for the centralized monitoring of mining, transportation, coal mining and other dynamic loads.
