摘　　要：对于采矿而言,爆破技术是提高采矿安全系数的关键。选取余华寺矿区一难采矿体作为试验对象,通过爆破试验对比,得出了采用不耦合装药爆破技术较适合于边角难采矿体的试验结论,具有较强的实用性和科学性。此研究成果对于同类矿山难采矿体的回采工作具有一定的指导意义。Blasting technology is the key factor to improve mining safety coefficient. Through blasting experi- mental comparison of the hard-to-mine orebody in Yuhuasi Mine Area, it can be concluded that the use of decoupling charge blasting is more suitable for the hard-to-mine boundary and corner orebody. This experimental result has strong practicability and seientificity, which has a certain guiding significance for similar hard-to-mine orebodies.
