The invention discloses high-strength waterproof concrete for mine operation and a preparation process thereof. The concrete comprises the following components: 390-420 kg/m < 3 > of cement, 60-86 kg/m < 3 > of asphalt resin, 660-725 kg/m < 3 > of sand, 1041-1050 kg/m < 3 > of stone, 142-156 kg/m < 3 > of water and 0-27.5 kg/m < 3 > of steel fiber. The components of the high-strength waterproof concrete for mine operation are arranged, the asphalt resin is introduced and reacted with the styrenated phenol, the divinyl benzene, the methacrylic acid and the hydroxyl polyamide, the asphalt resin is prepared, the fluidity of a concrete system is improved, the slump and stability of the prepared concrete are improved and kept, and the waterproof performance of the concrete is improved. The obdurability of the prepared concrete is improved, and the ductility of the concrete is improved.
本发明公开了一种矿井作业高强度防水型混凝土及其制备工艺，所述混凝土包括以下组分：390～420kg/m3水泥、60～86kg/m3沥青树脂、660～725kg/m3砂、1041～1050kg/m3石、142～156kg/m3水、0～27.5kg/m3钢纤维。本发明通过对矿井作业高强度防水型混凝土组分的设置，引入沥青树脂，并分别与苯乙烯化苯酚、二乙烯基苯、甲基丙烯酸，羟基聚酰胺反应，制得沥青树脂，提高混凝土体系的流动性，改善、保持所制混凝土的坍落度、稳定性，并改善所制混凝土的强韧性，提高其延性。
