The key to inrush water control engineering in coal mine lies in forming a water-resistant barrier through the pouring of aggregate, which achieves flow interception and reduction. In order to quantitatively describe the spatiotemporal evolution mech

Grouting after pouring aggregate can effectively control water inrush from coal and rock mass. The study on the deposition and migration law of aggregate in the water inrush channel from coal and rock mass is an important prerequisite to determine th

After the water inrush accident in coal mine tunnels, early-stage pouring of aggregate forms a high-resistance, low-permeability aggregate stacking, transforming the pipeline flow into percolation. In the later stage, grouting is carried out into the

Subway tunnels are mostly located in strata with an uneven pressure. This uneven pressure is usually manifested by lateral pressure coefficients less than 1. To adapt to the unevenness of the stratum load, in this study, we propose a new shield tunne

In rock mechanics, the problem of floor failure of a coal seam must be solved for mining coal above a confined aquifer. In this study, we aim to build an analytical mechanical model of coal-seam-floor failure based on plasticity theory and the Mohr
