1引言叶山矿由于矿床的形态（狭长）、地形（急倾斜）及周围环境（保护林、河流渔业权）等条件，采用爆破法进行端部处理受到限制。虽然该矿山端部处理过去大部分是采用机械或者低级炸药进行，但是用钢丝绳固定不稳固部分（围岩法）和利用低级炸药处理（支架法）等方法需要人工 1 INTRODUCTION The Yishan mine is limited in its end treatment by the blasting method because of the morphology of the deposit (slenderness), the topography (steep slope) and the surrounding environment (protection of forests and fishing rights of rivers). Although most of the mine’s end treatment was carried out by mechanical or low-level explosives, the method of using unsteady wire ropes (wall rock method) and the use of low-level explosive treatment (stent method)
