Abstract
Underground mining exploitation results in multiple effects on the rock mass surface, of which land deformation is particularly distinguishable. Mining deformations cause both changes to the environment, as well as damage to buildings and infrastructure. The measurement and description of these deformations is an important part of the safety assessment of the structures located on the land surface. In many cases, conducting these measurements may allow for detecting dangerous rock mass movements and therefore preventing construction disasters. It is worth noting that changes in inclination are one of the main indicators of deformations that are characteristic of the impact of mining exploitation on land surface and building structures. Deformation measurements are mostly carried out with surveying methods. The main objective of these methods is to obtain information about the scope and the size of the movements of points stabilized in the ground and on the building structures, and to determine real values of land deformation and the kinematics of their changes. However, these measurements do not provide a complete picture of the occurring changes. Rapid development of modem surveying technologies allow to introduce other measurement methods and tools. This paper presents a description of the sensors allowing for quasi-continuous monitoring of changes in inclinations of both land and structures. The test devices are SCA100T sensors of Dual Axis Inclinometer Series. These tools are made in MEMS technology, which is already successfully being used in other fields of science and technology. The devices were subject to careful testing procedures, the purpose of which was quality assessment of the conducted measurements. This procedure consisted of a comparative survey in different measurement ranges of the sensors with the statistical evaluation of the acquired research material. The results obtained during these tests allowed to hope for prompt application of these sensors in practice. The inclination sensors can compete with more expensive measurement solutions in spite of lower accuracy. Another advantage of the sensors of this type is the possibility to install them permanently on structures. This will result in the reduction of intervals between successive epochs of measurement, thus in achieving information which is currently unattainable when using standard surveying techniques.
