Micro-expansive blast hole blocking material for blasting construction as well as preparation and construction methods of micro-expansive blast hole blocking material
The invention discloses a micro-expansive blast hole blocking material for blasting construction, which is prepared from the following components in parts by weight: 40 to 63 parts of bentonite, 29 to 45 parts of river sand, 5 to 9 parts of expansive agent, 20 to 28 parts of water and 2 to 3 parts of fiber, the invention further correspondingly discloses a preparation and construction method. The explosive has the advantages of being large in expansion degree, good in micro-expansion performance, good in blocking effect, economical, rich in raw material source, easy to store and low in transportation cost, the explosive punching phenomenon in the blasting process is effectively avoided, and the energy utilization rate of the explosive is increased; and the requirements of demolition blasting and single blasting construction efficiency of drilling and blasting method excavation in a special geological environment are met and matched.
本发明公开一种用于爆破施工的微膨胀型炮孔堵塞材料，以重量份数计，包括：膨润土为40‑63份，河砂为29‑45份，膨胀剂为5‑9份，水为20‑28份，纤维2‑3份，其中，所述膨胀剂为CaO；还对应公开了其制备、施工方法；具备膨胀程度大、微膨胀性能良好、堵塞效果佳、经济、原材料来源丰富、易存储、运输成本少的优点，有效避免了爆破过程中的炸药冲孔现象，提高了炸药的能量利用率；满足和匹配了拆除爆破与特殊地质环境中钻爆法开挖的单个爆破施工效率要求。
