Abstract

The invention relates to the mining field of underground roadways in coal mines, in particular to a bolter drilling rig for mining, supporting and transporting parallel and rapid operations in coal mines. Balance and other issues, the middle frame is an arched structure, and the belt conveyor pin tooth drive traction mechanism connected with the mining traction adaptive belt conveyor is arranged symmetrically on both sides of the middle frame. The shaped space passes through and extends below the unloading part of the roadheader; it is equipped with 8 sets of drill booms, which are four sets of front anchor protection drill booms, two sets of rear anchor protection drill booms, and two sets of side support anchor protection drill booms. Arranged in rows, and each set of drill booms can slide for a certain displacement stroke to realize the height adjustment of the support row distance. Parallel operation can complete the bolt support of 6 tops and 2 gangs at one time, which shortens the support time and improves the support efficiency. It can also provide a channel for belt transportation to realize the parallel operation of excavation-support-transportation operations.

Description

Technical field [0001] The invention relates to the field of mining underground roadways in coal mines, in particular to a bolt drill carriage that integrates coal mining, support and transportation in parallel and rapid operations. Background technique [0002] With the gradual expansion of mine scale, the low excavation efficiency and the imbalance between mining and excavation ratio have become increasingly prominent. The tight production continuity has become a prominent problem restricting mine production and capacity expansion. At the same time, the continuous increase of excavation teams and personnel has made the coal mine safer. Management also brings great pressure. [0003] The traditional continuous mining production technology adopts double-lane digging, first digging and then supporting, production and support cannot be carried out at the same time. During the double-lane tunneling process, the equipment needs to call back the machine, which not only wastes the tunne...
