Awwad H. Justification mining technology of open pit for deposits with hight thickness layers (for example Jordan deposits)

Exposed geological conditions of El-Lajjun oil shale deposit, and also physical-mechanical properties of rocks, carried out analysis draft resolution by mining the field with concerning mining methods and complex mechanism. Carried out studies by selecting mining methods for horizontal areas with applying auto-conveying transports, set the dependence between ore transporting distance and the parameters of the open pit field with compact mining methods and applying auto-conveying transports operation. Set the development direction of mining works with mining El-Lajjun deposit. Carried out studies how efficient mining the field with applying drill-blasting and excavate the rocks directly from massive. Set the dependence between the quantities of excavators which necessary to mine the field, reserves values, and the specific resistance to digging the rocks. Based the rational level of explosive rocks crushing, with applying auto-conveying transports.
