摘要:
为解决煤矿岩巷掘进爆破施工作业中封孔工艺复杂、易冲孔以及掘进效率低等问题，设计了一种新型流体封孔材料与高效的封孔工艺。该封孔材料是由大理石粉、水与瓜尔胶三者按照70∶30∶0.15的质量比配制成的混合浆体，使用搅拌与泵送一体机，实现流体耦合封孔，并在顾北煤矿巷道掘进施工中得到应用。实验结果表明，该封孔材料具有黏度高、体系稳定和剪切变稀的流体特性，配合一体机使用，封孔工作效率提高304%，单循环进尺提高14.6%。封孔材料性能优良，封孔工艺简单，掘进效率与爆破效果得到明显提高。
Abstract:
In order to solve the problems of complex sealing technology, easy punching and low excavation efficiency in excavation blasting of rock drift in coal mine, a new type of fluid sealing material and a high efficiency sealing technology were designed. The sealing material is a mixed slurry composed of marble powder, water, and guar gum in a mass ratio of 70∶30∶0.15, which is transported by a mixing pump to achieve fluid coupling sealing. It has been applied in the excavation construction of tunnels in Gubei Coal Mine. The experimental results show that the sealing material has the fluid characteristics of high viscosity, stable system and shear thinning. When used with the integrated machine, the sealing efficiency is increased by 304%, and the single cycle footage is increased by 14.6%. The sealing material has excellent performances, the sealing process is simple, and the excavation efficiency and blasting outcome are obviously improved.
