The gas pressure measuring instrument
ACW-1 gas pressure measuring instrument is to study and master the coal seam gas emission and highlight the control theory and technology, the prevention of gas hazards and develop products. The new technology of slurry sealing, can be in all mine, different strata conditions, the real pressure accurately measured gas.
Application of gas pressure measuring instrument
For all kinds of mines, different rock conditions of coal seam gas pressure determination.
The working principle of the gas pressure measuring instrument
The two groups of rubber sealing, and the injection pressure is always higher than the gas pressure of the mucus to between two groups of sealing ring. Micro cracks around the borehole pressure mucus infiltration, due to the formation of the rubber ring seal mucus, sealing system mucus sealing gas. So tightly closed to prevent the leak of gas drilling, determined the coal seam gas pressure real.
Selection description
This equipment standard sealing depth 8m, length of mucus sealing hole section of 1.8m, such as the larger hole sealing depth or mucus sealing Kong Changdu, stating the order.
This equipment is designed in the setting of coal seam gas pressure is lower than 6Mpa, not suitable for the prediction of coal seam pressure is higher than 6Mpa.
