Oil phase for preparing on-site mixed ammonium nitrate fuel oil explosive from coal-to-oil intermediate product and preparation method of oil phase

The invention discloses an oil phase for preparing an on-site mixed ammonium nitrate fuel oil explosive by using a coal-to-oil intermediate product, which comprises the coal-to-oil intermediate product and a surfactant in a weight ratio of (93-97): (3-7), wherein the coal-to-oil intermediate product and the surfactant are metered and mixed, and the oil phase is generated after all the materials are uniformly mixed; and the coal-to-oil intermediate product is a semi-finished product in the coal-to-oil production process, namely, the coal-to-oil intermediate product. The oil-phase material prepared by the invention has the advantages of high flash point, safety in use, high calorific value, ability of facilitating detonation energy improvement, good oil-phase viscosity, ability of improving the free-running property of the ammonium nitrate fuel oil explosive, low cost, ability of reducing the cost and improving the efficiency, and the like. 一种用煤制油中间产品制备现场混装铵油炸药用油相包括煤制油中间产品、表面活性剂，二者的重量比在93-97:3-7，二者经计量混合，待物料全部均匀
