Coal mine underground thin spraying material manufacturing method, construction method and pneumatic guniting device
The invention discloses a coal mine underground thin spraying material manufacturing method, a construction method and a pneumatic guniting device, which relate to the technical field of coal mine underground production. An inorganic filler for the thin spraying material, high-standard white cement, polymer powder, quartz powder, titanium dioxide, redispersible latex powder, calcium sulphoaluminate and other auxiliaries are mixed in proportion. According to the spraying device, a left stirring barrel and a right stirring barrel work alternately; an inlet of the pneumatic guniting machine is connected with the bottoms of the left and right stirring barrels through a tee joint; an outlet of the pneumatic guniting machine is connected with a high-pressure pipe and a spray gun. The method hasthe beneficial effects that the defects of low construction speed, poor labor environment, high material consumption, high auxiliary transportation capacity, multiple potential safety hazards and thelike in the conventional concrete spraying technology are overcome. Thin spraying is combined with a novel guniting technology and a pneumatic guniting device, efficient construction is formed, safetyis ensured, the guniting speed and quality are improved, the working environment is improved, and meanwhile the cost is reduced.
煤矿井下薄喷料制作方法、施工方法及气动喷浆装置，涉及煤矿井下生产技术领域，薄喷料用无机填料、高标白水泥、聚合物粉体、石英粉、钛白粉、可再分散乳胶粉、硫铝酸钙和其它助剂，按比例混合。喷施装置包括：左、右搅拌桶交替工作；气动喷浆机入口与左、右搅拌桶的底部通过三通相连，气动喷浆机出口连接高压管及喷枪。本发明的有益效果是：解决了现有喷射混凝土技术存在施工速度慢，劳动环境差，材料消耗大，辅助运输量大，安全隐患多等缺点。薄喷料结合新型喷浆技术及气动喷浆装置，形成了施工高效，确保安全，提高了喷浆的速度和质量，改善了工作环境，同时降低了成本。
