It has been measured and summarized that using u-shaped full section round supporting while coal cutting up and down can ensure safety production.

The application of complex support form in reinforcement design of side slope;

Research on the suitable support form of deep gob-side entry in fully mechanized top coal caving mining

Through understanding the properties,deformation and destroying mechanisation of soft rocks,analyzing the stress characters of depth portion mining,comparing with the nowadays support forms,The difference of technclcgy and economicy that use different support forms is obtained by analyzing the existing conditions of every coal seam.

In the light of the complicated geological conditions, this paper analyzes on the effect of different supporting forms on the roof management, economic benefit, working environment and working strength of the workers, and the safety in production, etc.

This paper analyzes the failure mechanism of slope dome,discusses the design of slope supporting form,and processes and analyzes the test data of model,in order to achieve the purpose of optimizing supporting form design and to make the slope project safe and economic.

Selecting support pattern is an important component in support design for mining roadway in fully mechanized caving face.
