METHOD FOR MINE WORKING SUPPORT

摘要

A method for mine working support includes installation before zone of increased rock pressure along the working on main support frames of a reinforcement support through sequential rigid connection to each frame of main support of links, at least one long beam with shaped profile and rigid overlap joint of the links of the long beam to each other. Reinforcement support is installed with respective total rigidity. In case of one long beam it is placed in such a way that cross axis thereof is brought into coincidence with the vector of maximal rock pressure. In case of an even number of long beams those are placed in pairs symmetrically with respect to the vector of maximal rock pressure. In case of an odd number of long beams one of those is placed in such a way that cross axis thereof coincides with the vector of maximal rock pressure, and the other beams are placed in pairs symmetrically with respect to the vector.
