“…The causes of borehole blockage can be divided into two parts. Firstly, punching water volume is too little compared to punching crushed cinder, and the ability of returning water to discharge cinder is too weak [27], resulting in a large amount of cinder collecting in the borehole and the phenomenon of borehole blockage. Secondly, a large amount of cinder water collects in the borehole, and the mechanical properties are weakened under the effect of hydration and "argillization" [28], which adheres to the drill pipe and nozzle around the borehole intensifying the occurrence of blockage.…”

Taking hydraulic punching test of Zhaozhuang Mine as engineering background, by comparing the field application effects of different hydraulic punching processes, the relationship between coal moisture content around the borehole blockage and gas extraction effect was monitored and analyzed. The following conclusions were drawn: the occurrence of borehole blockage was the result of the comprehensive action of coal slag particle size and slag discharge capacity of punching return water. Blocking the borehole led to the accumulation of a large amount of punching high-pressure water and coal slag in the borehole, which compressed and infiltrated the surrounding coal body and reduced gas extraction efficiency of borehole. Under the condition of the same amount of coal produced by punching, the different punching methods led to the great difference in the influence radius of punching. The large flow three-stage coal-breaking hydraulic punching system developed according to the borehole blockage mechanism can effectively reduce the particle size of coal slag, increase the punching flow, effectively avoid borehole blockage, and improve gas extraction efficiency of borehole.

“…They also assessed the other two LBM approaches, and all three methods were evaluated by several known benchmarks. Stipic et al 28 proposed a multiplerelaxation-time lattice Boltzmann method for two-dimensional shallow water equations for sediment transport and morphology. The results compared with the measured data and the numerical results showed a good agreement.…”

Finite difference lattice Boltzmann method for modeling dam break debris flows

A finite difference lattice Boltzmann method (FDLBM) for the simulation of mud and debris flows for one-dimensional cases has been introduced. The proposed FDLBM recovers the generalized equations of mud and debris flows, that is, an unsteady one-dimensional Saint-Venant equation, including the effects of the non-Newtonian behavior of the mixture of water and soil, contraction–expansion losses (or large eddy loss), wind force, various geometries, and lateral inflow or outflow. The proposed FDLBM can be implemented for various non-Newtonian viscoplastic constitutive models of the studied mud and debris flows. The method is validated against previous studies for several benchmark cases, including steady-state problems, hydraulic jump tests, dam breaks with dry and wet beds, and slope dam break floods. Finally, the Anhui debris dam failure flood was investigated by this approach, and the results demonstrated a good agreement with the observed computational and field tests.
