[0041] As shown in Figures 1 to 9 The present embodiment provides a coal mine roadway tunneling machine-mounted anchor protection device, which comprises a machine-mounted base 1, a front anchor protection part 2, a power part 3, and a rear anchor protection part 4. The machine-mounted base 1 can be conveniently and quickly loaded on a tracked walking mechanism or a wheeled walking mechanism. The front anchor protection part 2 has three front drill boom rigs 208 arranged vertically and is mainly responsible for the anchor protection of the top of the coal roadway. The rear anchor protection part 4 has two rear drill boom rigs 404 arranged horizontally and is mainly responsible for the anchor protection of the sides of the coal roadway. The simultaneous action of the five drill boom rigs during the tunneling process can improve the tunneling efficiency of the coal roadway and achieve rapid tunneling.
