Research On Coal Bump Prevention Using Energy-absorption Bolts And Its Application

Aiming at the difficulties of ventilation in long term planning of Datong Coal Mine Group,study on ventilation system optimization of Tashan mine by using network version ventilation simulation system.Firstly,the network version of mine ventilation simulation system is studied in this paper,the basic theory,standard and general framework of the application are introduced emphatically.Secondly,the mine ventilation system survey was carried out in Tashan mine.At the same time,the network ventilation system of Tashan mine was established,then the test data are analyzed and studied,and carries out mine ventilation simulation basic data reliability test,for Tashan mine from main ventilator,ventilation capacity and ventilation system.There are four main aspects of main intake and ventilation Lane analysis and research.Finally,according to the actual production demand in the mine,long-term planning analysis and ventilation system optimization and transformation are carried out.It also simulates and formulates the plan to determine the reasonable mine ventilation mode and the angle of the main fan.And good field application results have been obtained.It also provides a reliable,convenient and quick decision means for the coal group,and provides a scientific basis for the designation of the ventilation scheme in the future.
