连续爆破排土是60年代初出现的一种挖土方法。它是直接利用燃料产生的热能对土壤做功,即用爆破方法剥离、破碎、抛移土壤,与传统的切土原理有本质差别。这种装置构造简单,易于制造,应用广泛,生产率高。目前,美、苏、日等国都已进行了这方面的试验研究工作。对这种理论,我们也进行了探索与试验。从试验看出利用爆破方法开挖是可行的,尤其 Continuous blasting and dumping is a method of excavation that occurred in the early 1960s. It is directly using the thermal energy generated by fuel to do work on the soil, that is, using the blasting method to peel, crush, and move the soil, which is fundamentally different from the traditional soil-cutting principle. This device is simple in construction, easy to manufacture, widely used, and high in productivity. At present, the United States, the Soviet Union, Japan and other countries have carried out experimental research in this area. For this theory, we also conducted exploration and experimentation. From the experiment, it is feasible to use the blasting method to excavate, especially
