我矿爆破装药是采用FZY-100型风动装药器,原使用粉状2号岩石硝铵炸药时,存在两个严重问题:一是由于粉状硝铵炸药返药率高,工作面药粉飞扬弥漫,劳动条件差,装完药后,操作人员普遍感觉口苦、流泪、皮肤发痒、便红尿、食欲不振,严重者引起肝脏功能减弱,眼睛模糊,患白内障等疾病;二是粉状硝铵炸药易结块,每次装药必须进行筛分和破碎,发生堵管时,还要敲打,劳动强度较大。因此,严重地影响风动装药器的推广使用。
I mine blasting charge is the use of FZY-100-type pneumatic chargers, the original use of powder No. 2 rock ammonium nitrate explosives, there are two serious problems: First, due to powdery ammonium nitrate explosives high rate of return, the face Powder filled filled, poor working conditions, after loading drugs, the operator generally feel bitter mouth, tears, itchy skin, then red urine, loss of appetite, severe liver function caused by weakened, blurred eyes, suffering from cataracts and other diseases; Powdered ammonium nitrate explosive caking, each charge must be sieved and broken, plugging occurred, but also beat, labor-intensive. Therefore, the serious impact on the popularization and use of pneumatic chargers.
