Quick-setting stemming material for filling blasting hole
The embodiment of the invention provides a quick-setting stemming material for filling blasting holes, and relates to the technical field of engineering blasting. The quick-setting stemming is composed of a composite material A and a composite material B. The quick-setting stemming composite material A comprises sulphoaluminate cement clinker, bentonite, a retarder and a dispersing agent. The quick-setting stemming composite material B is prepared from gypsum, quick lime, calcium carbonate, an accelerator and an early strength agent. When the quick-setting stemming material is used, slurry is prepared from the material A, the material B and water according to the mass ratio of 1: (1-3), and when the quick-setting stemming material is used, the slurry prepared from the material A and the slurry prepared from the material B are fully mixed according to the volume ratio of 1: 1, conveyed into a blast hole through a pump and a pipeline and quickly set into solid quick-setting stemming. The device is applied to a blasting operation construction scene, has the same filling effect and effect as manual stemming filling, can be pumped to achieve blasting operation blast hole filling mechanical operation, and is beneficial to improving the automatic operation level and the blasting effect of blasting operation.
本发明实施例提供一种用于爆破炮孔填塞的速凝炮泥材料，涉及工程爆破技术领域。由A、B两种复合料构成，所述速凝炮泥复合料A，包含：硫铝酸盐水泥熟料、膨润土、缓凝剂及分散剂。所述速凝炮泥复合料B，包含：生石膏、生石灰、碳酸钙、速凝剂及早强剂。所述速凝炮泥材料使用时，先分别将A料、B料与水按质量配比为1:(1～3)制备成浆液，使用时所述A料与B料制成的浆液按体积配比1:1充分混合，通过泵送和管路输送到炮孔中，并快速凝固成固体速凝炮泥。本发明应用于爆破作业施工场景中，具有与人工填塞炮泥同样的填塞作用和效果，可泵送实现爆破作业炮孔填塞机械化作业，有利于提升爆破作业的自动化作业水平和爆破效果。
