在铁路的旧线改造和复线修建中,往往要求工程进展迅速,而且安全可靠,周围交通设施、通讯线路、高压线以及城镇住房、人身财产不受破坏。所以,拆除混凝土、钢筋混凝土、砖砌建筑物等就不能单靠人工,也不能用一般爆破,而必须使用控制爆破,控制飞石、冲击波、地震波、噪声的危害,以达到高速安全,成本低,效果好的目的。目前,控制爆破已广泛地用于铁道工程,而爆破中采用的炸药仍是2~#岩石炸药,远远满足不了爆破要求,也影响了控制爆破的进一步发
In the construction of old railway lines and double-track railway lines, the construction projects often require rapid progress and are safe and reliable. The surrounding transportation facilities, communication lines, high-voltage lines and urban housing are not damaged. Therefore, demolition of concrete, reinforced concrete, brick buildings, etc. can not rely on artificial, but also can not be used in general blasting, but must use the control of blasting, flying stone, shock waves, seismic waves, noise hazards in order to achieve high speed and safety, low cost , The effect of good purpose. Currently, the control of blasting has been widely used in railway engineering, explosives used in blasting is still 2 ~ # rock explosives, far from meeting the blasting requirements, but also affect the further development of controlled blasting
