Chitosan coagulation aid had marked influences on floc form and floc strength,chitosan coagulation aid helped to make the floc dense and easy settlement,to make the floc strength and not easily broken.

Effects of process parameters on the gelcasting green strength and sintered density of stainless steel;

Aimed at controlling rocks in soft and thick coal seams, according to the occurrence of coal seam in 11151 working face in Liangbei coal mine, Shenhuo group, Henan province, the influence law between mining thickness, coal mass strength and the abutment pressure, rock deformation was simulated and analyzed with Flac 5.

A method for determination of coal mass strength through boring is proposed.

Then another formula is given to evaluate the coal strength decrease caused by.
