Study of a low-disturbance pressure-preserving corer and its coring performance in deep coal mining conditions
With the increasing depth of coal mining, the requirements for coring devices that maintain pressure are increasing. To adapt to the special environment in deep coal seams and improve the accuracy of testing gas content, a low-disturbance pressure-preserving corer was developed. The measurement of g...
