Spraying process of early-strength acid and alkali resistant spray coating for underground coal mine building
The invention provides a spraying process of an early-strength acid and alkali resistant spray coating for underground coal mine buildings. The early-strength acid and alkali-resistant spray coating specifically comprises 10 to 20 parts of cement, 5 to 10 parts of silica fume, 10 to 15 parts of sand, 8 to 16 parts of slag, 3 to 9 parts of bentonite, 5 to 12 parts of coal ash ceramsite, 3 to 8 parts of alkali-resistant glass long fiber, 6 to 13 parts of an early-strength acid and alkali-resistant agent, 7 to 15 parts of an accelerator and 5 to 8 parts of a water reducing agent, and the early-strength acid and alkali-resistant agent is composed of an early-strength agent and an acid and alkali-resistant cement additive. The spraying method for spraying the early-strength acid-alkali-resistant spraying material by adopting the upper spraying equipment comprises the following specific steps: S1, proportioning and mixing coarse aggregate and fine aggregate on a well, bagging, transporting to the underground by a mine car, transporting other auxiliary materials such as cement to the underground by the mine car, and mixing; s2, chiseling is conducted; s3, the well wall is scanned; and S4, spraying is conducted. According to the technology, the scabbling process can be automatically completed before spraying, then the well wall recess is scanned and analyzed, the uniform spraying process of the well wall is achieved, and the continuous mixing and spraying process can be achieved.
本发明提供一种井下煤矿建筑的早强耐酸碱喷涂料的喷涂工艺，早强耐酸碱喷涂料具体包括10‑20份水泥、5‑10微硅粉、10‑15份的砂子、8‑16份的矿渣、3‑9份的膨润土、5‑12份的煤灰陶粒、3‑8份的耐碱玻璃长纤维、6‑13份的早强耐酸碱剂、7‑15份的速凝剂和5‑8份的减水剂，其中早强耐酸碱剂由早强剂和耐酸碱水泥添加剂，采用上喷涂设备喷涂早强耐酸碱喷涂料的喷涂具体步骤为：S1、粗骨料和细骨料在井上完成配比和混合，装袋后由矿车运至井下，水泥等其它添加辅料也均有矿车运至井下，进行混料；S2、凿毛；S3、扫描井壁；S4、喷涂。该工艺能够在喷涂前自动化的完成凿毛过程，随后对井壁凹陷进行扫描分析，实现井壁均匀性的喷涂过程，并且能够实现连续式混料和喷涂过程。
