Thin spraying material for inorganic coal mine and construction method of thin spraying material
The invention provides an inorganic thin spraying material for a coal mine, and belongs to the technical field of spraying materials. The thin spraying material for the inorganic coal mine comprises the following components: 42.5-grade quick-hardening early-strength sulphoaluminate cement, 328-type redispersible latex powder, S95 mineral powder, glass fibers and the balance of 200-mesh quartz powder and quicklime powder. Mixing with water, stirring and pressurizing; the method has the advantages that the supporting thickness is small, and only 5 mm is needed; and in the construction process, the thickness of the thin spraying support is greatly reduced compared with that of the sprayed concrete support, so that the corresponding material preparation and transportation volume are greatly reduced. Under the same supporting condition, the weight of the thin spraying supporting material is only 7-10% of the weight of the sprayed concrete supporting material; on the other hand, thin spraying supporting equipment is small in size, light in weight and easy to transport; and the spraying operation speed is high, manpower resources are few, the construction period is short, and the material cost and the construction cost are both lower than those of a conventional supporting material.
本发明提出一种无机煤矿用薄喷材料，属于喷涂材料技术领域；所述无机煤矿用薄喷材料组分包括42.5级快硬早强硫铝酸盐水泥、328型可再分散性乳胶粉、S95矿粉以及玻璃纤维，余量为200目石英粉以及生石灰粉；通过与水混合搅拌加压制成；具有支护厚度薄，只需要5mm的优点；且施工时由于薄喷支护厚度比喷射混凝土支护厚度大大减小，相应的材料准备及运输量都大为减少。在同等支护条件下，薄喷支护材料重量仅为喷射混凝土支护材料重量的7~10％；另一方面，薄喷支护设备体积小、重量轻，容易运输；且喷涂作业速度快，人力资源少，工期短，使其材料成本以及施工成本均低于常规支护材料。
