【Abstract】 Contrapose the characteristic of shallow depth of embedding " two-hard" ultra heavy coal seam,Reasonable pattern of hydraulic support is determined in full-mechanized mining face.Key technologies of hydraulic support are researched by the numerical simulation,industrial trial indicate that hydraulic support well adapted to fully mechanized top-coal caving in "two-hard" ultra heavy coal seam,and good economic benefits is got.更多还原
