Micro-foaming inorganic spraying material and coal mine underground spraying method
The invention provides a micro-foaming inorganic spraying material and an underground coal mine spraying method, and relates to the technical field of underground coal mine guniting. The micro-foaming inorganic spraying material provided by the invention is prepared from the following components in parts by weight: 85-90 parts of a cementing material and 10-15 parts of a composite additive, the composite admixture comprises special clay, a dry powder foaming agent and a coagulation-accelerating and exciting admixture. The micro-foaming inorganic spraying material provided by the invention is different from cement mortar guniting and high-molecular spraying materials, and can better meet the requirements of fire prevention and extinguishment, quick air leakage stoppage and rescue and relief work in an underground coal mine.
本发明提供了一种微发泡无机喷涂材料和煤矿井下喷涂的方法，涉及煤矿井下喷浆技术领域。本发明提供的微发泡无机喷涂材料，以重量份数计，包括胶凝材料85～90份，复合外加剂10～15份；所述复合外加剂包括特种粘土、干粉发泡剂和促凝激发外加剂。本发明提供的微发泡无机喷涂材料不同于水泥砂浆喷浆和高分子喷涂材料，能够更好地满足煤矿井下防灭火快速堵漏风和抢险救灾需求。
