硐室爆破的填塞是保证爆破效果和安全必不可少的一道工序。我矿安全规程原规定,硐室爆破的填塞物必须用矿岩石块。由于硐室规格小而深,往硐里运送石块困难,而且受到时间的限制,实际上大多用草袋,每袋装石块十多公斤,往硐里传送;堵塞横巷和主巷大多只用稻草。尽管这样,填塞过程用人很多,还保证不了填塞质量,爆破效果和安全受到影响。每次爆 Chamber blasting packing is to ensure the blasting effect and safety of an essential process.

Due to the small and deep chamber specifications, stone transportation to the cave is difficult, and subject to time constraints, in fact, most of the straw bag, bagged more than 10 kg of stone, to the hole in the transmission; Only straw.
