The use of a tactile sensory system in connecting counter workings

At present, the problem of advancing mine workings when connecting them is that after advancing, the workings often coincide within the project workings’ contours, which causes a significant increase of the costs, diminishes the safety and creates ecological issues. The instrumental methods cannot provide quality determination of the workings advance direction when connecting the workings, thus the work safety deteriorates, and the cost of eliminating the consequences of the non-quality connection increases. To improve the ways of connecting the workings, either the existing technology should be modified or a new technology is needed. The purpose of the study is to develop a new technology for determining the direction of the counter workings when connecting the workings. The technology involves a tactile sensory system of man and is realized by the comparison of the degree of the rock surface vibration effect on a human palm at different points of the face. The vibration is created by drilling a blast-hole, and it is measured by applying the palm to the face. The suggested technology can enhance the advance exactness and safety, as well as increase the mineral output and reduce the costs of advancing the counter mine workings due to the decrease in the deviation from the target direction when connecting the workings. The technology can be used when advancing counter mine workings and connecting the workings in ore and alluvial mines.
