LBY-3 Roof Separation Instrument—

The roof separation instrument produced by Taian Jiufang Mining Equipment Co., Ltd. is a device used to monitor the displacement generated when the rock layers of a coal mine roof separate. It can monitor roof separation displacement and subsidence to prevent roof accidents. The instrument features high precision, intuitive display, low cost, simple installation, and time-saving and labor-saving observation. It provides coal mine engineers and inspection personnel with the necessary basis for understanding the length and tensile strength of anchor bolts, as well as the rationality and economy of the anchor bolts and cables used. The roof separation indicator reflects the values of multiple fixed devices in the roof hole, which change with the rock layers, through measuring steel cables to a reading device installed on the roof surface.
