The Design of Gas Drainage Holes? Opening Parameters Intelligent Measurement and Control System for Coal Mine

Drilling Project is a huge project in coal main. Now mine is still measured in the method of artificial construction and acceptance. It is difficult to ensure that construction can meet the design parameters. The hole depth of gas drainage hole is generally no more than 100m, so it can be considered that the aperture is approximately parallel with the opening position. During the construction, we only require the opening position to meet the design requirements. In view of this situation, this article introduces the principle and design of a kind of drilling parameters intelligent measurement and control system for coal mine. This system uses the sins based on gyro and accelerometer of the rig to measure the azimuth and inclination, which also uses the hole depth measurement system to measure the depth of the drilling rig, and with the help of ZigBee technology and the existing Ethernet underground real-time transmits to the surface. This helps the management of surface supervise the real-time monitor and then manage the drilling status. This design can improve the accuracy of the construction of coal mine drilling and construction management while reducing administrative costs.
