综采工作面过断层技术措施应用

Application of technical measures for passing through faults in fully mechanized mining face

基于屯兰矿12503工作面过F1断层带期间,工作面出现煤岩体破碎、支架陷低、端面距加大等现象,为了保证工作面安全快速过F1断层带,通过技术研究,对工作面过F1断层带提出了合理有效的安全回采工艺及技术措施,通过实际应用,取得了显著应用成效。

Based on the phenomenon of coal and rock breaking,low support sinking and increasing end face distance in the working face of 12503 coal mine passing through F1 fault zone,in order to ensure the safe and rapid passing of the working face through F1 fault zone,reasonable and effective safe mining technology and technical measures are put forward for the working face passing through F1 fault zone through technical research,and remarkable application results are achieved through practical application.
