| Abstract: | Taking the scope of underground Mining Causing surface movement as elliptic area, this paper puts forward the basic principles and concrete steps to design the coal pillar of buildings protection by influencing ellispe method. This method is suitable for any shapes of protected as well as the condition of larger chang of elevation of base rock and coal seam. It is a new method to design coal pillar of buildings protection in coal mine. |
