Abstract

The invention relates to the technical field of coal mine roadway supporting, and provides a temporary supporting and drilling-grouting integrated anchor rod composite supporting system and a construction method. The temporary supporting and drilling-grouting integrated anchor rod composite supporting system comprises a first supporting device and a second supporting device, wherein the first supporting device comprises a sucker frame, a drilling pipe and a vacuum pipe; and the second supporting device comprises an anchor rod mechanism, a driving mechanism, a grouting mechanism and a propelling mechanism. Negative pressure can be rapidly formed in roadway surrounding rock, the surrounding rock is reliably and temporarily supported through atmospheric pressure, and the supporting effect isimproved; and drilling, grouting anchoring and pre-tightening of the anchor rod supporting device are integrated, the structure is simple, operation is convenient, the construction procedure is simplified, the supporting effect is guaranteed, the supporting efficiency is improved, and automatic operation is achieved.

Description

technical field [0001] The invention relates to the technical field of coal mine roadway support, in particular to a bolt composite support system and construction method integrating temporary support and drilling and injection. Background technique [0002] The existing temporary support of coal mine roadways is mainly mechanical support devices. These devices are generally installed on the excavation equipment. It is widely used and can solve the demand for temporary support to a certain extent. [0003] Existing temporary support plays the role of shielding and protection after the deformation of the surrounding rock, and cannot generate active and rapid support force for the newly excavated area before the deformation of the surrounding rock. [0004] Bolt support can effectively control the deformation of surrounding rock, and has been widely used in coal mines, metal mines and other fields at home and abroad. Taking coal mine roadway support as an example, the existi...
