Proposal to look for an up/down asymmetry in atmospheric neutrinos beyond Multi-GeV region with existing experimental data [PDF]
, 1999 We discuss a possible test of neutrino oscillation hypothesis by proposing the combined analysis of high energy atmospheric neutrino induced muon events that have been detected around horizontal direction in the Kolar Gold Field (KGF) underground site ...

A multiscale flux basis for mortar mixed discretizations of reduced Darcy-Forchheimer fracture models [PDF]
, 2018 In this paper, a multiscale flux basis algorithm is developed to efficiently solve a flow problem in fractured porous media. Here, we take into account a mixed-dimensional setting of the discrete fracture matrix model, where the fracture network is ...

Surrounding Rock Stability Control Technology of Soft Rock Roadway Passing Water Conductive Faul
Meikuang Anquan, 2020 When soft rock roadway passes the water conductive fault fracture zone, the surrounding rock often faces grea tinstability risks. Based on this, FLAC3D is used to perform numerical simulation analysis on the stress, deformation and failure characteristics when it passes through the fault considering the softening effect of mudstone and siltstone by ...

The effect of burnt rock on inclined shaft in shallow coal seam and its control technology
Energy Science & Engineering, 2019 Burnt rock is a geo‐material widely existed in many countries. After the rock mass is burned, the fracture is developed, the structure is destroyed, the integrity and strength are reduced, and a good water storage space is formed in suitable hydration ...
