摘要
研制性能优良、成本低廉的充填材料是巷旁充填的关键技术.本文介绍了一种新型巷旁充填材料——以煤矸石、粉煤灰为主体的天然硬石膏混合充填材料,其胶凝与力学性能及配比参数优化试验研究,并阐述了该充填材料应用前景.
A kind of pacling material of good-performance and low-cost is the key to the success of roadway-side packing. In this paper, presentation is given of a new-type roadway-side material which is basically a natural-anhyduite one comprising chiefly mine gobs ang fine coal powders. Discussion is also made about its gelatinization and mechanics. Experments and tests are done to aptimize its preparation parameters. Finally, the prospects about the application of the material to roadway-side packing are foretold.
