The invention discloses an anchor bolt hole thread driving expanding drill pipe for mining. The drill pipe comprises a chambering cutter, a sleeve, a push-pull rod, a drilling machine connecting shaft and a push-pull driving sleeve, wherein the push-pull rod is coaxially arranged in the sleeve; the rear end of the chambering cutter is connected with the front end of the push-pull rod; two long holes are formed in the front side of the sleeve; a push structure is arranged at the front end of the sleeve; the push-pull driving sleeve coaxially extends into and is connected with the interior of an internal thread pipe through threads; a handle is arranged at the rear end of the push-pull driving sleeve; the rear end of the push-pull rod and the front end of the drilling machine connecting shaft are coaxially fixedly connected with each other; an external thread structure is arranged on the external circumference of the drilling machine connecting shaft; a driving guide block which is positioned in the internal thread pipe and is matched with the front end of the push-pull driving sleeve in a pushing manner is arranged on the push-pull rod. The drill pipe is simple to operate, low in cost and stable in chambering performance, and the cutter can be automatically opened and effectively retracted. The drill pipe can effectively solve the problem of failure of an anchor rod caused by sliding between the anchor rod and a hole wall, can effectively improve the safety situation of a mine, and improves the production efficiency of the mine.
