Selective cross shaft road header could move its boom up and down or left and right, and belongs to single point cutting machine.

Organization modeling and simulation of boom type roadheader's horizontal hunting;

Visualization monitoring of boom type roadheader cutting path;

The control model of the manipulator for the mine boom type roadheader had an uncertainty and nonlinear with the easy modeling,the uncertainty of the hydraulic system parameters,loading disturbance of the mechanism model and asymmetric cylinder controlled by the symmetric valves.

The development process of boom-type roadheader in our country is introduced,reviews the satus and trends of boom-type roadheader at home and abroad.

In order to monitor and control cutting section automatically,the boom-type roadheader was simplified as roboticized model.

Introduces the recent situation of boom-type roadheader at home and abroad,and the development of its intelligent controlling.

Advances and trends on boom-type excavators;

Detection and transform modeling for sectional-formation geometrical dimensions of boom-type excavators;

Selection of main technical parameters of boom roadheader;

Cutting technique of boom roadheaders;

According to the stress state influenced on the picks of cutting head on boom roadheader in different operation conditions, the matched relation between the oscillating force and cutting force of cutting head as well as its general value selection range are studied in order to provide theoretical basis of designing swing mechanism of boom roadheader.
