mining conditions

FEM NTA coupling model is set up for simulation of mining conditions at great mining height with an overlying rocks of low tensile strength.

Mining half a century, the total of resources reduced, the mining conditions constantly worsening, even dry.

The adaption of mining method is the similarity between the mining conditions of designed mine and adaption capacity.

After entering the soft coal mining, mining conditions have changed fully mechanized caving face in tandem with changes in the layout.

Prediction parameters of the model vary with mining conditions and the size of goaf, so it is amended in part.

With complicated mining conditions, Huainan coal mine area is under bad threat of mine gas disasters.

Based on the geo-mining conditions of the site, a local strategy was formulated to counter the menace of the encountered lateral movement.

For all sorts of different coal mining conditions, we should choose to suitable hydraulic support type adapting to the new environment.

It can give a certain reference for exploiting to the mine with similar mining conditions.

I know I am smart, have talent, but only because I was white, I have performance and mining conditions of these endowments.
