In the western mining region, weakly cemented rock layers above the coal seams often lead to frequent catastrophic accidents during mining due to their instability. To address this, this paper analyzes the movement characteristics of surrounding rock

The instability of jointed rock masses has been a persistent concern in China’s underground geotechnical engineering, particularly regarding rock mass instability triggered by structural activation, such as faulting. This form of instability consti

The instability of hard and brittle rock often leads to disastrous consequences in underground engineering. Under various surrounding rock pressure conditions, in situ stress induces corresponding deformation and damage to the floor post-mining. Ther

This paper deals with the optimum classifier and the performance evaluation by the Bayesianapproach. Gaussian population with unknown parameters is assumed. The conditional density given a limited sample of the population has a relationship to the mu
