For open pit coal mines subsidence of the surrounding area and landslides are among the most common mininginduced catastrophic geohazards These largescale geohazards are related to both hydrogeological and geotechnical parameters and they cause substantial damage A major challenge to managing these hazards is that the factors that trigger these two phenomena are diametrically opposed... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
