摘要
介绍了伪斜柔性掩护支架采煤法在煤层倾角小于矸石安息角工作面的应用。对该方法进行了可行性论证,提出了解决掩护支架移架困难的措施,总结出了适合该方法应用的支架结构,并通过实例证明,使用该方法取得的经济效益大大优于长壁采煤法,改变了过去认为在倾斜煤层中小于矸石安息角时不宜采用该方法的观点。
This pa-per describes the application of false-in clined flexible shield min ing system in coal face with seam pitch less than rest angle of waste.Reliability demon-stration of this mining system was con ducted,the measures for the ad vance of shield support were put forward and the support structure suitable for false-in clined flexible shield mining system in coal face with seam pitch less than rest angle of waste was sum marized.The economic ben efit ob tained by using this method is much better than that by longwall mining.
