| Most of our traditional open-pit mining is adopted to help ease mining,mining craftwork such smaller slope angles and thus help bring a lot of defects,such as excessiveexploitation of the initial infrastructure works,is not conducive to early see mine,variouseconomic indicators poor preparation time is too long a new level.Baotou Steel GroupBarun mine as newly developed large-scale mining,if it continue this process willinevitably affect the mining companies of various economic indicators.Blasting and miningsub-assembly technology to help improve the working slope angle,saving drilling andblasting costs,help as soon as possible see mine,the mine will greatly improve theeconomic efficiency.Steep slope mining popular talk is used to help carry out the work of the more steepjob,this "steep"is relative to the traditional sense of the "slow"is concerned,and itsinclination angle of work about24oto about36o,and some even and the final slope angleequal or similar.Its technical objective is the existing equipment and personnel under theconditions and circumstances,see the mine as soon as possible,try to postpone subsequentstripping peak,the initial production stripping ratio to a minimum to reduce the initialinvestment as soon as possible to withdraw the initial investment for the benefit of miningenterprises long-term investment and development.Working slope angle stripping processselection is open-pit mining,mining equipment selection and shipment of the three majordomestic equipment manufacturing level and ability,a comprehensive reflection of thelevel of corporate management.At the same time,its choice will directly determine thereasonableness of open mining enterprises infrastructure stripping quantity, infrastructurecycle,infrastructure investment,the loan repayment capacity and long-term productionoperations level.Visible, it is a pull one vital body surface mining comprehensive technicaland economic parameters and indicators.Therefore,its study and optimization,has a veryimportant role and significance.Open pit mining operation of the main equipment ismounted shovel.Shovel movable rate directly affects the efficiency of mining enterprisesand mining costs.How and paragraph mining conditions,an effective arrangement shovel,is a matter of efficiency in all mining work,so shovel work of research is also a toppriority.To affect the work Slope Angle various parameters assigned different values,proposed several groups of different combinations of parameters,and use the software maychange the present value of the curve and the inclination angle of work distributiondomains.The main methods of analysis shovel work in steep slope mining car runningunder the corresponding initial face mode and prepare for steep slope mining process isready to implement the corresponding work.This topic in a few groups of different inclination angle of work combined Barun contrastand the production capacity of existing equipment on the basis of the final results of the work tohelp the most appropriate slope angle of22.6o,in addition,an equivalent change in the domainare overlapping,different equivalence class has a corresponding distribution of the domain.Shovel work study concluded that steep slope mining advance only once whencompleted,shovels have multi-step vertical upward mobility,in advancing the process tomobilize fewer,so the steep slope mining shovels to help mobilize more frequently than slowmined less. |
