Recently, the National Mine Product Safety Marking Center “on-site evaluation of intrinsically safe electrical products†was held at Henan Polytechnic University. An expert group headed by Tang Yong, director of the National Coal Mine Explosion-proof and Safety Product Quality Supervision and Inspection Center, conducted an on-site assessment of the center's “CHP50M coal seam gas content quick tester†and “CPD8M coal seam gas pressure testerâ€.
"CPD8M coal seam gas pressure tester" is suitable for automatic testing of coal seam gas pressure, eliminating the need for manual data recording and other cumbersome procedures in "Direct Measurement Method". "CHP50M coal seam gas rapid measuring instrument" is suitable for rapid measurement of coal seam gas content in coal mines, without the need for laboratory measurements of coal samples, the determination period of 15-30 minutes; instrument built-in rechargeable battery can ensure its continuous work more than 8 hours, the product The supporting software can directly read the data and perform necessary analysis. It has the advantages of safety, reliability, advanced technology, convenient operation and accurate measurement. This product uses the current mainstream microcontroller as the main control chip, the use of professional dust, explosion-proof technology and high-precision AD conversion system, can accurately determine the underground coal seam gas pressure; built-in rechargeable battery can ensure that the logging pressure drilled within 30 days of the coal seam Gas pressure, and drawn into a pressure recovery curve for viewing at any time, with convenient operation, intuitive image, safe and reliable, easy to carry, low energy consumption, high precision.
Both of these products were jointly developed by the Engineering Technology Center of the Ministry of Education of the Coal Mine Disaster Prevention and Rescue and Disaster Relief of Henan Polytechnic University and the Gas Prevention Technology and Equipment Research Institute of Henan Polytechnic University. As a "prospect probe" to prevent gas disasters, this product is applied to the production line and will play a catalytic role in quickly measuring coal seam gas content and gas pressure, and reducing gas as the "culprit" of the coal mine accident.
