摘　　要：根据待拆除煤仓、皮带走廊的结构特点和拆除要求以及其周围的环境条件,设计煤仓和皮带走廊同时爆破拆除,并于爆破前将两者被拆与保留部分采用爆破和人工的方法预先解体,煤仓向北倾倒,走廊原地塌落。同时进行了参数、爆破网路等合理设计和精心施工,加强安全防护,拆除爆破达到了预想效果。Based on the structural features of coal bunker and its belt corridor and the requirement from the demolition engineering and the environmental conditions, the program of simultaneously demolishing the bunker and its belt corridor was designed. The both were manually divided before blasting. The coal bunker collapsed towards the north and the corridor collapsed in situ. The blasting parameters,ignition network and so on were conducted carefully. Expected demolition results were obtained.
