目前，在我国采用爆破拔管的技术方法较多。但是，一般的爆破方法都很繁琐，需要专门加工爆破筒，选择爆破技术参数等。井管炸破后，砾料进入井内，还要下管利用空气压缩机进行排砾，使砾料排出井外后，才能拔管，这样就提高了工人劳动强度和钻探成本。下面结合实例，介绍一种简易的爆破方法供参考。 At present, there are many technical methods used for extubating in China. However, the general method of blasting is very tedious. It requires specialized blasting drums and blasting technology parameters. After the well pipe is blown, the gravel material enters the well, and the air compressor is also used to grind the gravel, so that the gravel can be discharged out of the well before the pipe can be removed. This increases the labor intensity and drilling cost of the workers. The following examples, introduced a simple blasting method for reference.
