Description

technical field

[0001] The invention relates to a coal mine roadway excavation machine and a coal mine excavation machine, in particular to a small multifunctional roadheader capable of realizing continuous roadway excavation and coal mine comprehensive mining operations. Background technique

[0002] With the continuous development of coal mines, there are more and more low-lying coal seams. At present, the height of large and medium-sized roadheaders is more than 1.5m, and the width is more than 2m. It is inconvenient to use in the mining of coal seams. Many coal mines implement blasting mining in this working condition. The risk of blasting mining is very high, and the operating efficiency seriously affects the speed of roadway excavation and comprehensive mining; the cutting head and The cutting arm is tightly connected, and it is impossible to replace multiple functional devices to complete multifunctional operations. The utilization rate of the equipment is not high, a...
