An explosion proof and environment protective oil (gas) refueling equipment includes an oil (gas) storage tank connected with a refueling machine. The inner chamber of the oil (gas) storage tank is filled with an explosion-proof material, which is a multi-layer material unit made of high porosity lamellar materials, with a fixed supporting part being set in this material unit for fixing and supporting the unit, a skid is set under the oil (gas) storage tank and the oil (gas) refueling machine. A plurality of said units is orderly installed in the inner chamber of the oil storage tank, with reasonable installing method and structure. With the fixed supporting part being installed in the unit, the explosion-proof material units have adequate strength and elasticity so as to effectively prevent the collapse and distortion of the high porosity lamellar material in the tank, thus the unexpected explosion hazards that may be caused by naked flame, static electricity, welding, gunshot, collision and faulty operation can be prevented and safety of oil (gas) refueling equipment can be ensured. The explosion-proof material unit being covered with a metal protective mesh which can effectively prevent scraps from getting into the medium in the tank and causing harmful effect on the content medium thereof.
