|
Abstract Connotation and three kinds of basic support form of strong shell-body support in soft rock roadway is put forward in this paper. The support principle is analyzed by dynamics method，on the basis of which，calculation formula of reasonable bolt length，interval and diameter of bolt and its impact on support structure is educed. The result indicates that effect of “short，thin and dense” bolt support precedes that of general bolt. The presented study result is approved in soft rock roadway support practice in Longkou mine bureau.
