DESIGN AND TEST RESULT OF THE NEW SOLUTION HYDRAULIC ROOF SUPPORT FOR LOW SEAMS
Abstract
The subject of thin seams exploitation is complex problem, and in reality it encounters several problems such as technical, ergonomic, and economic barriers. They refer mainly to combined longwalls where human presence is required at the site, and the most important problem is the issue of limited workspace in the longwall roadways. It generates engineering and organizational problems, especially during the launch and removal of the longwall roadways. Having considered the abovementioned, the Department of Mining, Dressing and Transport Machines, AGH in Krakow, has begun research whose main objective is development and testing of a new structure of powered support for thin seams. In this paper virtual models of new hydraulic roof support and conception of a structure of control system were presented as well as the test results of new construction hydraulic roof support. Research in this field was conducted for the project entitled Studies of development of innovation hydraulic roof support for low seams. The project is funded by the National Center of Research and Development (NCBiR).
