煤矿巷道掘进多采用钻爆法施工,而炸药的种类也很单一,即采用粉状铵梯炸药,随着科学技术的进步,一种新型的炸药已经问世,即乳化炸药,由于其优点很多,所以今后巷道掘进所用的粉状铵梯炸药必将由乳化炸药所代替,下面就针对我矿使用乳化炸药情况进行浅述。 Coal mine tunnel boring more drilling and blasting construction, and the type of explosives is also very simple, that is, powdered ammonium ladder explosives, with the progress of science and technology, a new type of explosives has come out, that is, emulsion explosives, because of its many advantages, Therefore, future use of roadway tunneling powdered ammonium ladder explosives will be replaced by emulsion explosives, the following for my mine use emulsion explosives case described.
