摘　　要：以某矿3110三软超长炮采工作面为分析对象,从工作面顶板来压特征、支架工作阻力状况和超前支护工作阻力等方面对该工作面矿压显现规律进行研究,为类似地质条件的三软超长炮采工作面的高产、高效、安全生产提供技术条件和理论支持。Taking 3110 super long blasting face in three soft coal seams of some Mine as analysis object,in this paper,strata behavior regularity was analysed from the aspects of pressure from the features of roof weighting,supporting resistance situation and the work resistance of advanced timbering and so on.At last,the paper provided the technical advantage and theoretical support for high yield,efficient,safe production of other three soft coal seams of super long blasting face.
