Study on Mining Pressure Appearance Rule of Shallow Seam Fully-mechanized Mining Face in Yanghuopan Coal Mine

To solve the problem of controlling mine pressure of fully-mechanized face in shallow seam and analyze operation characteristics of supports, mine pressure monitoring system whose type is KMJ30 was put in use for monitoring mine pressure of 30108 fullymechanized working surface. By analyzing the measured data of supports during the period of primary mining, normal mining and the end of mining, this article concluds: the average step distance of first weighting and periodic weighting, the distribution of face tendency pressure, the pressure of whole fullymechanized face and the mining pressure of special terrain, and master the appearance rule of coal face pressure. It is of a great importance to provide the direction for reliable mining and safe production.
