The invention relates to underground engineering protective equipment, and in particular relates to an underground engineering glass fibre reinforced plastic composite protective door. The underground engineering glass fibre reinforced plastic composite protective door comprises a door frame and a door body, wherein the door frame and the door body are made of glass fibre reinforced plastic materials; the door frame and the door body are formed by compounding a lead boron polyethylene plate between two layers of glass fibre reinforced plastics; and the glass fibre reinforced plastic material is composed of 60-70% of glass fibre, 20-30% of anti-neutron fibre and 3-10% of X and gamma-ray resistant fibre. The protective door disclosed by the invention is not only light in dead weight and flexible to open and close but also high in impact wave resistance and good in nuclear radiation resistant effect; by adopting composite fibre of the glass fibre and the anti-radiation fibre, the glass fibre reinforced plastic has nuclear radiation resistant effect; the lead boron polyethylene plate is compounded between two layers of glass fibre reinforced plastic materials, and therefore, the shielding rate of the protective door to nuclear radiation is 97% or more.
