On the basis of analysis of mining plans and field studies at mines of JSC SUEK-Kuzbass, it
is shown that in conditions of increasing the size of excavation columns during the …

In longwall mining, ventilation is considered one of the more effective means for controlling
gases and dust. In order to study longwall ventilation in a controlled environment …

Protective layer mining (PLM) is one of the most effective regional measures against gas
outburst, and the most preferred technique to prevent and control gas outburst. This paper …

Permeability is one of the key factors involved in the optimization of oil and gas production in
fractured porous media. Understanding the loss in permeability influenced by the fracture …

Protective coal layer (PCL) mining is a preferred regional method for preventing coal and
gas outbursts; stress‐relief of PCL mining is the prerequisite of pressure‐relief gas drainage …

It is very important from the point of view of gas control and production safety to efficiently
extract gas from stress-relief fractures in the initial phase of the longwall working face. In the …

To explore the structure evolution of overlying strata and pressure characteristics of coal
mining with large dip angle, the basic roof mechanical model was established that based on …

Severe gas hazards are increasing in deep mining areas, and there exists an enormous
traditional challenge for protected seam mining. In this work, we conducted a multifaceted …
