The invention relates to a grouting material composition for an inner layer of a coal mine tunnel, a tunnel section device and a construction method, the grouting material composition comprises cement used as a main material and a novel inorganic grouting reinforcing agent used for improving the cement, the main material composition of the grouting material composition is realized through the cement, and through the novel inorganic grouting reinforcing agent, the construction efficiency is improved. The cement is modified by the environment temperature and humidity in the mine tunnel, and the technical problem that cement and quartz sand are used, so that the environment temperature and humidity in the mine tunnel have great influence on the cement coagulation process is solved, so that the strength of the inner layer of the mine tunnel is improved. 一种用于煤矿巷道内层的注浆材料组合物、巷道断面装置和施工方法，包含有用于作为主料的水泥、用于作为对水泥进行改良的新型无机注浆用添加固剂，通过水泥，实现了对注浆材料组合物的主要物质构成，通过新型无机注浆用添加固剂，实现了在矿井巷道中的环境温度和湿度对水泥进行改性处理，解决了对都是使用水泥和石英砂从而由于在矿井巷道中的环境温度
