WBY-10 Roof Separation Instrument—

The roof separation instrument produced by Taian Jiufang Mining Equipment Co., Ltd. is a device used to monitor the displacement caused by the separation of rock layers in the coal mine roof. It can monitor roof separation displacement and subsidence to prevent roof accidents. The instrument features high accuracy, intuitive display, low cost, simple installation, and time-saving and labor-saving observation. It provides coal mine workers with the necessary basis for detecting the length and tensile strength of anchor bolts, and for understanding 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 borehole, which change with the rock layers, through measuring steel cables to the reading device installed on the roof surface.
