| Abstract: | The orebody is moderately inclined and thin in Hongda mining company.In order to explore reasonable extraction process and improve mining technology as well as the level of mechanization,experimental research on panel mechanized false-inclined stripped mining has been carried out.The paper describes in detail the components,preparation and cutting and extraction process of the method.Field industrial test results show that the production capacity of the panel is 377 t/d,the mining loss rate and the ore dilution rate are 15 % and 7.16 % respectively ,achieving desired test results and directly increasing the profits of the test panel by 819 900 yuan annually. |
