Tunneling system

Abstract

The invention provides a tunneling system, and belongs to the technical field of tunneling machines. The anchor protection platform is arranged in a space above the heading machine, and the anchor protection platform can move along with the heading machine; the anchor protection platform can be used for installing an anchor protection device and providing a walking area needed by personnel during construction. An operation area and an equipment installation area which can move along with the heading machine are created in the air above the heading machine, various anchor protection devices can be installed on the anchor protection platform, a place for walking and construction control is provided for constructors, and the constructors are made to be just like conducting construction on the ground in the construction process. And compared with a ground anchor protection device, the anchor protection device can move along with the heading machine, and the anchor protection work is more flexible. And the tunneling efficiency is further improved.

Description

technical field [0001] The invention belongs to the technical field of roadheading machines, and in particular relates to a roadheading system. Background technique [0002] At present, with the gradual improvement of coal mine mechanization, comprehensive mechanization has been fully realized in the mining operation of the mining operation face, and the driving unit has also been put into use in the excavation operation face. However, due to the generally poor geological conditions of coal mines in China, the roof is broken, and the empty roof distance is small. At present, the alternate operation of roadheader and bolter is mainly carried out. During the tunneling operation, the bolting speed is slower than the cutting speed of the roadheader, which seriously restricts the tunneling. Efficiency, the contradiction of mining imbalance is increasingly prominent, and the degree of automation is low. [0003] The bolter in the alternate operation is divided into bolter and man...

Problems solved by technology

However, due to the generally poor geological conditions of coal mines in China, the roof is broken, and the empty roof distance is small. At present, the alternate operation of roadheader and bolter is mainly carried out. During the tunneling operation, the bolting speed is slower than the cutting speed of the roadheader, which seriously restricts the tunneling. Efficiency, the contradiction of mining imbalance has become increasingly prominent, and the degree of automation is low

[0003] The bolter in the alternate operation is divided into bolter and manual pneumatic bolter. Only the bolter is used for anchor protection work. When the boring machine completes the cutting work in the front, the machine is moved back, and the bolter is close to the head for bolting. 1. For the construction work of the anchor cable, when the support is completed, the bolter is retracted, and the roadheader is performing the cutting operation of the next cycle. Frequent front and back adjustments greatly restrict the excavation efficiency
