摘要
Abstract
The mine open-off cut should be very safety because it is a wide-spanned place where the mining facilities are located. In the past, the supporting of open-off cut used to be log shed. Since the space is limited, the facilities fixing efficiency and safety are influenced greatly. The rock layer above coal bed of Malan mine 2th coal bed is composed of multiple layers of different rock beds or thin coal beds. So if using log shed to support open-off cut, the deformation of surrounding would be large and the space would be limited, then the facilities fixing efficiency would be low and the log consume would be huge. The method of bolt + stay rope is an effective way. It can improve the facilities fixing environment greatly as well as efficiency and safety reliability. At the same time, the cost and working intensity are lowed geratly.关键词
