摘　　要：以某矿2303厚煤层坚硬顶板工作面为分析对象,从工作面顶板来压特征、支柱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,为具有类似地质条件的厚煤层坚硬顶板工作面的高产、高效及安全生产提供技术条件和理论支持。No.2303 face with thick coal Strata behavior regularity is analyzed seam and stiff roof in a certain coal from some aspects, such as the pressure mine is researched features of the old roof, the support resistance situation and the effective work resistance and so on. At last, the technical advantage and theoretical support are provided for high yield, high efficient, and safe production of other thick coal seam and stiff roof working faces.
