陡峭石质路堑爆破施工控制

On blasting construction control of steep on stone cutting

结合具体工程实例,介绍了复杂条件下的路堑爆破施工控制,针对深孔松动爆破结合预裂爆破和缓冲控制爆破工艺进行了阐述,根据爆破效果指出采用该方法提高了石方爆破质量,满足了进度及安全要求,并节约了成本,值得推广。

Combining with the engineering examples, the paper introduces the stone cutting blasting construction control in complicated conditions, illustrates the combination of long hole loose blasting with the presplitting blasting and buffer control blasting craft, and points out the adoption of the method can improve the stone blasting quality according to the blasting effect, so as to meet the speed and safety requirement and save the costs, and extend further.
