药室爆破的堵塞,是保证爆破效果与安全必不可少的一道工序。堵塞物一般用矿、岩石块。由于药室规格一般较小较深,往里运送堵塞物料比较困难。我矿进行峒室爆破设计的矿块和顶板剥离块段多处于山顶或山腰,地形陡峭,峒口缺乏堆放场地,因而实际堵塞长度往往达不到爆破设计要求。有时从山坡上砍些灌木,茅草作为堵塞物,爆破时,从峒口飞出石 Blockage of the pharmacy chamber blasting is an indispensable step in ensuring the blasting effect and safety. General blockage with ore, rock blocks. As the size of the drug chamber is generally smaller and deeper, it is more difficult to transport the clogged material in and out. My mine blasting chamber blasting block design and roof peeling blocks are mostly in the mountain or mountainside, the steep terrain, the mouth of the lack of stacking sites, and thus the actual length of the blockage is often not up to blasting design requirements. Sometimes cut some shrubs from the hillside, thatch as a blockage, blasting, flying out of the mouth of the stone
