Top Coal Caving Roof Support
Patent Number: ZL200920026190.9
The top coal caving roof support is added with a set of hydraulic mechanical device on the basis of ordinary hydraulic support. The top coal is now drawn by the top coal caving mechanism on the shield beam.
As our patented product, this equipment has a high degree of automation, high coal production volume of single coalface, and high supporting strength, which is suitable for thick and ultra-thick coal seams.
Standard Compliant: MT312-2000, MT/T154.5-1996
