Taymylyrskoe coal deposit is located in north-west of Republic of Sakha (Yakutia). Coal reserves are by category А+В+С1 162956 thousand t, C2 – 160100 thousand t. The grade of coal is D. Coal seam lies gently dipping with angles up to 5°, roof seam is represented in gray sandstone, the soil consists of sand-shale. Contacts of the coal seam as a roof, and the soil are quite sharp. The temperature of the surrounding rocks is -5 ° -8 °. The distance from the formation to the surface is from 0 to 200m. It is necessary to solve a number of complex issues for mining of Taymylyrskoe coal deposit. One of the problems is the difficulty in roof control. The method for roof control breaking bad and poorly managed is developed in Institute of Mining matter in the North. The method consists in the fact that vibrator unit through which primary landing roof made is mounted on the surface over goaf. Remote monitoring of the displacement of the roof rocks are carried out at the same time with the work of dipole installation.
