以现场矿压观测资料为基础 ,结合矿山压力理论对国内第一个超长综放面来压规律及特点进行简单分析 ,初步掌握了超长综放面的来压规律 ;并从来压步距、强度、支架压力及运行状况等方面与普通综放面进行对比分析 ,得出超长综放面有别于普通综放面的来压特征 ,可为今后设计、布置和回采类似工作面提供科学依据。
Based on the observation data of the mine pressure, combined with the mine pressure theory, the author analyzes the regularity and characteristics of the pressure in the first ultra-long fully mechanized caving face in China. Strength, bracket pressure and operating conditions of the fully mechanized caving face were compared with those of the common caving face, and the conclusion was drawn that the pressure characteristics of the ultra-long caving face different from that of the general fully mechanized caving face can be provided for the design, layout and recovery of similar working face in the future Scientific basis.
