Parallel operation process of digging, protecting and anchoring and parallel operation system of digging, protecting and anchoring

Abstract

The invention provides a parallel operation process of digging, protecting and anchoring and a parallel operation system of digging, protecting and anchoring. The parallel operation process of digging, protecting and anchoring comprises the following steps that a roadway is continuously cut by a roadheader; the roadheader completes the cutting operation of at least one anchor rod row spacing; a frame moving trolley lifts an end bracket; the roadheader moves at least one anchor rod row spacing; the frame moving trolley moves at least one anchor rod row spacing of the end bracket; and the end bracket is fixed; and temporary support and anchoring support of the roadway are completed. Through the technical scheme of the parallel operation process of digging, protecting and anchoring and the parallel operation system of digging, protecting and anchoring, a highly automated, intelligent and integrated high-efficiency comprehensive tunneling production system is realized. The parallel operation process of digging, protecting and anchoring and the parallel operation system of digging, protecting and anchoring are mainly suitable for the driving construction of a coal roadway and a half-coal and half-rock roadway supported by an anchor net in coal mines, and further are applicable to similar tunnel construction in non-coal mines.

Description

technical field [0001] The invention relates to the technical field of coal mine roadway mining, in particular to a parallel operation process of excavation, protection and anchoring and a parallel operation system of excavation, protection and anchoring. Background technique [0002] With the rapid improvement of my country's overall industrial technical level and equipment manufacturing level, the mining technology level and equipment manufacturing industry of the coal industry have also been greatly improved, especially the coal mining technology and equipment level of my country represented by Shenhua Group, Has reached the international leading level. [0003] However, compared with the level of fully mechanized mining technology, the level of fully mechanized excavation technology and equipment is relatively low, basically still at the level of the late 1990s. At present, the main equipment of most fully mechanized excavation working faces is still roadheader+ The stan...

AI Technical Summary

Problems solved by technology

The start-up rate is low, usually the cutting time of the roadheader only accounts for about 30% of the total working time, it is difficult to match the rapidly improving fully mechanized mining technology and equipment level, and the excavation imbalance is serious
