An adaptive neuro fuzzy inference system to model the uniaxial compressive strength of cemented hydraulic backfill
(National Mining University, 2018-06-30)Purpose. The purpose of this paper is to develop the models for predicting the uniaxial compressive strength (UCS) of cemented hydraulic backfill (CHB), a widely used technique for filling underground voids created by ... -
Choice and substantiation of stable crown shapes in deep-level iron ore mining
(National Mining University, 2018-12-30)Purpose. The aim of the paper is to select and substantiate stable shapes of crown pillars through determining regularities of rock pressure impacts on their stability depending on the crown shapes, mining depths and iron ... -
Prognosis of surface deformation by the influence function method in terms of Paroseni mine (Romania)
(National Mining University, 2018-06-30)Purpose. The paper analyzes a problem of surface deformation as a result of low-inclined seam underground mining in Paroseni mine, Romania. Solving this problem makes it possible to predict the effects of the underground ... -
The rate of deformation development in the rock massif on the basis of surveying monitoring on the earth surface
(National Mining University, 2017-03-30)Purpose. Basing on the instrumental surveying measurement, to determine the rate of tensile strain displacements in the rock mass, and to use the obtained data for controlling rock pressure and ensuring job safety. Methods. ... -
Towards safer mining: the role of modelling software to find missing persons after a mine collapse
(National Mining University, 2018-06-30)Purpose. The purpose of the study is to apply science and technology to determine the most likely location of a container in which three miners were trapped after the Lily mine disaster. Following the collapse of the Crown ...
