Study On The Changcheng Wopu Coal Mine Exploration's Influence On The Original Ground Stress Field And On The Keerkang Oil Field

This papermainly studied the original region ground stress field and the coal mine exploration'saffect to theoriginal region ground stress field for their overlapping position.
