Abstract

The invention discloses rock stratum splitting equipment and a roadway top rock stratum splitting method. The rock stratum splitting equipment comprises a drilling machine, a plurality of drill rods, a bidirectional splitting device, a water tank and a high-pressure water pump, wherein the drill rods are sequentially connected through threads, and the bidirectional splitting device is used for bidirectionally splitting a rock stratum. According to the rock stratum splitting equipment and the roadway top rock stratum splitting method, the high-pressure water pump is adopted for supplying high-pressure water to the two-way splitting device, splitting rods are pushed out through the high-pressure water to act on the hole wall of the drill hole of the roadway top rock stratum so as to split the roadway top rock stratum to form gaps, operation is convenient, and safety is high.

Description

technical field [0001] The invention relates to the technical field of roadway roof cutting and splitting for pressure relief, in particular to a rock splitting device and a roadway top rock splitting method. Background technique [0002] In the process of coal mining, sometimes it is necessary to split the roadway top rock formation to relieve pressure. At present, blasting is mainly used for pressure relief in underground gob-side entry retaining in coal mines. Explosives need to be installed in drill holes in rock formations, which is inefficient, labor-intensive, and has potential safety hazards. [0003] In view of this, it becomes necessary to provide a rock formation splitting equipment and a roadway top rock splitting method with convenient operation and high safety. Contents of the invention [0004] The object of the present invention is to provide a rock formation splitting equipment and a roadway top rock splitting method with convenient operation and high saf...
