Problems solved by technology

However, the use of roadheaders for roadway excavation also brings a new problem. Due to the large size of roadheaders, traditional roadway support equipment and support methods cannot provide effective support for the roadway when the roadheader exists, especially If the newly exposed roof above the roadheader cannot be supported in time, it is extremely easy to cause the roof to collapse and cause safety accidents

Abstract

The invention relates to the technical field of hydraulic supports for supporting, in particular to a hydraulic support for roadway supporting. Roadway supporting can be provided for coal mine excavating and backstopping. The hydraulic support comprises multiple groups of top beams, multiple groups of transverse beams and multiple groups of hydraulic supporting columns, each group of transverse beams is located below the corresponding group of top beams, each group of hydraulic supporting columns is located below the transverse beams to support the corresponding group of transverse beams, and the multiple groups of transverse beams and the multiple groups of top beams are combined to form multiple groups of mutually connected movable mechanisms. According to the hydraulic support for roadway supporting, efficient, safe, reliable and omni-directional supporting for a roadway can be achieved by the aid of a simple optimal structure, safe and reliable supporting guarantee can be provided for advancing of mining machinery such as heading machines, meanwhile, the mobile flexibility is extremely large, moving adjustment can be performed according to actual requirements of excavating and mining, thereby, safe, reliable, convenient and flexible guarantee can be provided for roadway supporting of coal mine excavating and backstopping, and the working efficiency which is related to excavating and mining can be greatly increased.

Description

technical field [0001] The invention relates to the technical field of hydraulic support for support, in particular to a hydraulic support for roadway support, which provides roadway support for coal mine excavation and mining. Background technique [0002] In coal mining, in order to ensure that coal mining activities can be carried out normally, the underground roadway is a necessary and important project as a passage for pedestrians, ventilation, transportation, drainage and other activities. In the preparation work of the coal mining face, the upper and lower troughs and cut holes must be developed first, so as to provide coal transportation and ventilation channels for the mining face. With the vigorous promotion of roadheaders, roadway excavation is increasingly carried out by roadheaders, and its efficiency and safety are obviously superior to traditional blasting excavation methods. However, the use of roadheaders for roadway excavation also brings a new problem. Du...
