Production tolerances determining the accuracy of surveying surveys at coal mines

Abstract

When designing, producing and evaluating surveying works, the question constantly arises as to what is the criterion of their necessary and sufficient accuracy. The rich practice of underground mining allows to assert that such criterion is technically correct and economically feasible solution of production tasks related to the field operation. Surveying works carried out at a mining enterprise are designed to provide it with the necessary mining engineering, mining geometry and geodetic data. Naturally, the volume and accuracy of these data should be determined by the production requirements, which are expressed in the values of production tolerances. Conducting surveying work without full consideration of the established tolerances can lead to a number of complications of the process of mining of minerals - to disrupt the normal operation of the enterprise. It should be said that overestimated accuracy of surveying works is as harmful for production as insufficient; both the first and the second lead to significant losses of time and money, to violation of normal surveying service of mining operations.
