Fully-mechanized excavation roadway quick excavation process based on duplex multi-group self-moving walking type temporary support

Abstract

The invention provides a fully-mechanized excavation roadway quick excavation process based on a duplex multi-group self-moving walking type temporary support. The process is completed by adopting an intelligent cantilever type heading machine, a four-drill-arm crawler drilling and anchoring vehicle, the duplex multi-group self-moving walking type temporary support, a reversed loader and a conveyor in a combined mode. The process comprises the specific implementation steps of preparation work of the heading machine, heading of the heading machine, temporary support and frame moving, anchoring support, transportation, assistance and the like, the heading operation and the frame moving operation are continuously carried out, parallel coordination operation of heading and anchor rod support is achieved, and the anchoring support operation, the heading operation and the temporary support can be continuously carried out without a coupling relation in space and time. The overall speed of coal mine roadway heading is increased, the unmanned degree of comprehensive coal mining work is improved, and the problems of mining proportion imbalance, mining connection looseness and the like are solved.

Description

technical field [0001] The invention belongs to the cooperative operation technology of fully mechanized tunnel excavation, supporting and anchoring, and in particular relates to an intelligent cantilever type roadheader which is used together with a four-arm crawler drill and anchor truck and a double-connected multi-group self-moving step-type temporary support for underground coal mines. Fully mechanized roadway rapid excavation technology. Background technique [0002] "Rich in coal, poor in oil, and low in gas" is the basic feature of my country's energy structure. In the past and for a period of time in the future, coal is still the most important part of my country's energy, and the demand for coal will continue to increase. At the same time The coal industry is required to continue to develop in the direction of high-yield, high-efficiency and safe production. In recent years, the degree of fully mechanized mining in my country's key coal mines has continued to rise,...
