摘　　要：程潮铁矿采用无底柱分段崩落法开采,BQ-100型装药器装药,工人劳动强度大,机械化水平低,爆破质量不稳定。为提高机械化作业水平,降低工人劳动强度,改善爆破质量,程潮铁矿引进CharmecMC 605 DA型装药台车。经过井下中深孔装药爆破试验,确定装药台车合理的工人配置为4人,适用的炸药为岩石膨化硝铵炸药。最佳工艺技术参数为炸药含水率控制在5%左右,罐内压力0.50~0.55 MPa,助推风压0.40~0.42 MPa,退管速度0.30~0.34 m/s,返粉率控制在10%左右。通过比较分析2种装药设备的优缺点,装药台车的机械化作业水平和安全性高于BQ-100型装药器,降低了工人劳动强度,爆破质量优良率提高了3%。该装药台车对国内类似矿山实现上向中深孔装药的机械化和自动化有一定的借鉴意义。Chengchao Iron Mine adopts non-pillar sublevel caving method and BQ-100 type charg⁃ing device.The labor intensity of workers is high,the level of mechanization is low,and the blasting quality is unstable.In order to improve the level of mechanized operation,reduce the labor intensity of workers and improve the blasting quality,Chengchao Iron Mine introduced Charmec MC 605 DA charging trolley.Through the underground medium and deep hole charging blasting test,it is determined that the reasonable allocation of workers for the charging trolley is 4,and the applicable explosive is rock expanded ammonium nitrate explosive.The optimum technological parameters are as follows:the water content of explosive is controlled at about 5%,the pressure in tank is 0.50~0.55 MPa,the boost air pressure is 0.40~0.42 MPa,the pipe withdrawal speed is 0.30~0.34 m/s,and the powder return rate is controlled at about 10%.By compar⁃ing and analyzing the advantages and disadvantages of the two kinds of charging equipment,the mecha⁃nized operation level and safety of the charging trolley are higher than those of the BQ-100 type charging device,which reduces the labor intensity of workers and increases the excellent rate of blasting quality by 3%.The charging trolley has a certain reference significance for similar mines in China to realize the mech⁃anization and automation of upward medium and deep hole charging.
