瑞典尼特罗·诺贝尔机械公司在最近几年中发展了许多装药系统,这些系统仍在井下进行试验。更有希望的发展之一是用于全机械化井下装药的EG—33型自动装药机。另一项发展是用于大孔装药的“推进式装药器”。尼特罗·诺贝尔公司与瑞典采矿公司的LKAB矿合作,正在基鲁纳沃拉矿对自动装药机进行试验。此外,这种装药机样机的修改型正在马姆贝里耶特矿进行试验。像瑞典的和国外的大多数矿山一样,LKAB矿目前是人工装药。一个人站在平台上,用手把装药软管插入炮孔。当软管下到孔底时,用铵油炸药填满炮孔。然后用每个炮孔中的引爆炸药和 Nilotra Nobel Machinery Company of Sweden has developed a number of charge systems in recent years and these systems are still being tested underground. One of the more promising developments is the EG-33 automatic filling machine for full mechanized downhole loading. Another development is the “push-in” for large-bore charge. Nitrono Nobel, in cooperation with the LKAB mine of the Swedish mining company, is experimenting with automatic chargers at the Kiruna Navarra mine. In addition, a modification of this prototype machine is being tested at the Mammbayite mine. Like most mines in Sweden and abroad, the LKAB mine is currently manned. A man standing on the platform, the charge hose inserted into the hole by hand. When the hose down to the bottom of the hole, use ammonium dynamite to fill the hole. Then detonate the explosives and in each gun hole
