METHOD FOR EVALUATING FILLING QUALITY AT WORKING FACE OF SOLID-FILLING COAL MINING

摘要

Provided is a method for evaluating the filling quality at a working face of solid-filling coal mining. Firstly, a solid-filling coal mining control object is determined by a solid-filling coal mining application purpose; secondly, corresponding evaluation indexes for different filling mining purposes are selected according to the control object; then, a theoretically required range of each evaluation index is determined from the engineering geological parameters at the working face and the control object; and finally, a comparative analysis of the theoretical value and the actual value of the evaluation index is performed to obtain a quality evaluation result of the filling working face. This method provides a reference for effective evaluation of the filling quality at a working face of solid-filling coal mining, has an important significance for ensuring successful implementation of solid-filling coal mining, and is particularly suitable for the evaluation of the filling quality at a working face of solid-filling coal mining with a solid such as gangue and pulverized coal ash.
