Installation Method of LBY-2 Roof Separation Instrument

LBY-2 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 accuracy, intuitive display, low cost, simple installation, and time-saving observation. It provides scientific data for coal mine engineers and inspection personnel to understand 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 borehole, which change with rock layer movements, through measuring steel cables onto a reading device installed on the roof surface. The roof separation instrument serves mines with comprehensive product support;
