Abstract

The invention discloses a continuous excavating equipment and process for roadways. The continuous excavating equipment comprises an intelligent operation assembly line composed of a cantilever roadheader, a belt conveyor, a continuous loading device and a tramcar. The continuous excavating process includes steps of breaking rock by a cutting mechanism of the cantilever roadheader, loading falling gangue and transporting to the outside constantly to the belt conveyor so that the gangue can directly fall into the tramcar from the tail end after waste rocks are separated; dragging the tramcar which is fully loaded to a waste rock transporting roadway and transporting the tramcar to discharge the waste rock on the ground; dragging another unloaded tramcar on a no-load tramcar rail to a waste rock loading tramcar rail along a turnout rail, and starting a new round of loading and discharging; and dragging the discharged tramcar to the no-load tramcar rail for standby application. By the continuous excavating equipment process for roadways, mechanical construction level of the roadways can be effectively improved, construction process is simplified, excavating efficiency is improved, labor intensity is reduced, working environment is improved, operation safety is improved, and continuous excavating of the roadways is truly realized.

Description

Technical field [0001] The invention relates to an equipment and process for excavating underground roadways in coal mines, in particular to an equipment and process for comprehensive mechanized continuous excavation of underground semi-coal and rock roadways and rock roadways. Background technique [0002] At present, there are two main methods for tunnel excavation in domestic coal mines: roadheader tunneling and drilling and blasting method, among which drilling and blasting method accounts for more than 90%. The drilling and blasting method has the disadvantages of small tunneling section, slow construction speed, poor roadway quality, low mechanization, high labor intensity of workers, low safety and reliability, and poor working environment. Therefore, many technicians in the industry continue to improve the technology of roadway boring machines. Level, and strive to improve the roadway construction technology. The improvement of roadway excavation efficiency is not only d...
