The invention provides a split type drilling apparatus comprising an airplane body. The airplane body consists of an airplane head part, a front airplane body part, a middle airplane body part, a rear airplane body part, a rear airplane end, and a tail part that are connected mutually and detachably. Wings arranged at the left side and the right side of the airplane body are connected with the middle airplane body part detachably. The airplane body includes an upper part and a lower part; the upper part includes a plurality of parallel upper semicircular skeletons arranged vertically and the lower part includes a plurality of parallel lower semicircular skeletons arranged vertically; and the upper semicircular skeletons and the lower semicircular skeletons have same sizes and are arranged in an up-down corresponding manner. Fuel gas generators breathing fire to the tail are arranged below the wings. According to the invention, the airplane body is divided into a plurality of detachably parts, so that the airplane body can be installed and transported conveniently. The fuel gas generators breathing fire to the tail are arranged inside an engine compartment; an ignition system carries out ignition automatically; and on the basis of the signal, a relay carries out controlling to complete the ignition process.
