2021-11-28 · Promoting the ability of anti-bursting of the confining rock of a coal roadway is of significant importance to the safe production of a coal mine. In particular, in deep-buried coal mines, highly frequent rock burst occurs due to large earth pressure and complex geological conditions, which needs serious improvement. This paper investigated a type of confining rock

The advantages of clay mineral modification methods for ...

The natural and modified forms of clay minerals have an exceptional ability to remove different contaminants. However, the modification methods can improve the clay mineral adsorption properties that consequently increase more adsorption sites and functional groups to adsorb different environmental pollutants.

The minerals are valuable in their pure form, but in the earth they are mixed with other, unwanted rocks and minerals. This mix of rock and minerals is usually carried away from the mine together, then later processed and refined to isolate the desired mineral. The two major categories of modern mining include surface mining and underground mining.

Diatomite: Its Characterization, Modifications and ...

Diatomite rock is a loose, earthy or loosely cemented porous and lightweight rock of sedimentary origin, mainly formed by fragments of armor (skeletons) of diatom algae: diatomea and radiolaria. Diatomite is a microscopic diatom alga whose size ranges from 0.75 to 1500 m; sometimes this rock is called infusorial earth, kieselguhr, or mountain meal.
