Fan Qing-xia

Abstract

Pointing to main problems in application of structural parameters of(10~13)m×10 m stope in Meishan Iron Ore Mine,the experimental tests of increasing stope's structural parameters have been done.Measures in the field of drilling blasting and achievements are explained.The necessity of increasing stope's structural parameters and optimizing parameters of drilling blasting are pointed out.
