| Abstract: | The monitoring of roof-off-the-strata is one of the most important factors in bolting support roadway.In this paper,the existing methods and the monitoring instrument for roof-off-the-strata are included and analyzed.Based on the measuring principle of grating,a new roof-off-the-strata sensor is described.This sensor and underground substation can make up the monitoring system of roof-off-the-strata.Then the monitoring on the ground can be accomplished.This system has been applied to the on-line experiment on the ground and in the pit at the LvLiangDianPing mining area.The experimentation results show that this system runs stably and the data transmit accurately. |
