The work deals with developing a pit wall displacement sensor. The analysis of the existing solutions has been carried out, their advantages and disadvantages have been given. An imitation laboratory bench has been presented with which use there were studied rock displacement sensors. The sensor has been developed on the basis of a new method of controlling additional optical losses. A source of coherent optical radiation with the wavelength of 1310 or 1550 nm has been used in the experiments. The sensor has a plastic case with two input adapters for optical connectors. One of them moves, the other does not move, and an elastic element is located between them. The light wave generated by the radiation source passes through the sensor and returns to the optical power meter. The sensor has been calibrated using a measuring scale with a division value of 1 mm. Depending on the distance between the ends of the optical fiber, the losses vary linearly. The use of a single-mode optical fiber for determining the displacement of the sides of a quarry is very promising, since the fiber-optic sensors developed on its basis have a sufficiently high accuracy, measurement speed, and good linearity of characteristics. The geotechnical parameters of the displacement of the sides of the open pit, which determine the danger of collapses that occur during the operation of technological equipment in the course of mining, are considered.
