To investigate the lateral deformation characteristics of dam bedrock scoured by river flow
environments, standard specimens were prepared using cored sandstone from the barrage …

This paper presents an integrated approach for theoretical analysis and numerical modeling
to investigate the ground response mechanism of entries and control methods induced by …

In recent years, strong seisms are triggered frequently during deep coal mining process,
which seriously threatens the safety of underground miners and ground residents, as well as …

In the N00 coal mining method, one of the most critical issues is ensuring the safety of the
entry behind the working face. To address this challenge, various roof control techniques …

Introduction Soft rock mining roadways are severely deformed and damaged during coal
mining. Blindly increasing the support strength not only has little effect but also wastes …

Continuous mining and continuous backfilling (CMCB) is an effective method to control
surface subsidence and implement resource utilization of solid waste. To address the issue …

To explore the mechanism of roof directional breaking in gob-side entry formed
automatically without coal pillars, the numerical simulation was used to study the …

This paper utilizes physical and numerical model experiments to study the deformation and
failure mechanisms of goaf-side entries driving adjacent to longwall top coal caving …

Strong mining tremors (SMTs) frequently occur in super-thick strata near the goaf when
mining. Since 2021, there have been three consecutive SMTs with magnitude greater than …

Close extra-thick coal seams are subject to the broken overburden of mined coal seams,
and the deformation and damage of the roadways is serious, which affects the safe …
