| 2. | Application and test on controlled blasting in draw on slope of open - pit 露天采场临近边坡控制爆破试验及应用 |
| 3. | Study on side slope stability in mine jiaozuoshiyuan open of henan province 河南焦作柿园矿区露天采场边坡稳定性分析 |
| 4. | The mine is adopted to open - mining and underground - mining jointly , and the open - mine is divided into north and south stope 由于历史因素,矿山开采本关先南露天采场后北露天采场原则进行。 |
| 5. | The criterion of the damage of the eastern slope of open pit of tongshankou mining by blasting vibration can be judged by dynamic stress ratios ( dsr ) 铜山口矿露天采场东帮岩体爆破震动破坏情况可使用动态应力比判据来判别; 5 |
| 6. | Abstract : the cause for blasting toes in open stope of tiegukeng mine was analyzed , the corresponding modification measures were proposed and the blasting effect of the stope were improved 文摘:对铁古坑矿露天采场爆破产生根底的原因进行了分析研究,提出了相应的改进措施,使采场爆破效果得到了改善。 |
| 7. | Stereographic technique is used in the analysis of the footwall slope in the open - pit of bangmoshan iron mine . the slope fracture mode and the slipping direction of unstable blocks are given and the stable slope angle is calculated to be 46 运用赤平极射投影的方法,对棒磨山铁矿露天采场下盘边坡进行了稳定性分析,给出了边坡破坏模式和不稳定块体的滑动方向,并推算稳定边坡角为46 。 |
| 8. | Secondly , the optimum blast parameters of each parts of open pit and spreading law of the wave of blasting vibration on the east of open pit was studied . furthermore , the paper presented the method of decreasing blasting ground vibration as follows . 1 通过大规模的现场试验和爆破震动测试,得出了铜山口铜矿露天采场各区段的优化爆破参数以及生产爆破产生的地震波在东帮的传播规律,在此基础上提出了降震措施并得出如下主要结论: 1 |
| 9. | One of the existing problems of the mine at present is : when the south open stope is over in 2005 , where does the open north stope start for the sake of optimizing economic benefit and social benefit and environmental benefit of the mine facing to this problem , based on the large number real data of mine , in view of fuzzy attribute and complexity attribute existing in mine production , this paper applies fuzzy multi - attributes decision method to a lot of feasible technology , economy rational for schemes to appraise to proposes 当前矿山生产存在的问题之一是:南露天采场将于2005年开采结束,何处启动北露天采场,才能使得矿山经济效益、社会效益、环境效益保持最优化?针对铜绿山铜铁矿北露天矿何处启动最优这一问题,本文在收集大量铜矿山生产实际资料基础上,针对矿山生产中存在的模糊性和复杂性,提出运用模糊多属性决策方法对多个技术可行、经济合理方案进行评价。 |
| 10. | Abstract : this paper gives the fe simulating analysis of the effect on road construction in the process of mine open - cut , analysis and evaluates stability of road foundation during many rock material steps excavation , concludes that the different conditions , for example , the rock caves , steps and the dis tance between the steps and road have influence on the road foundation stability 文摘:针对矿山在地下开采转为露天开采过程中,原地采区域在露天采场台阶开挖过程中对露天采场公路建设及运营的影响,进行了数值模拟分析,并对通过各种岩体介质的露天采场公路路基在台阶开挖和汽车运营过程中的稳定性进行了分析评价,得出了在不同条件下,如空洞地区、台阶材料介质、材料界面、开挖台阶与公路距离等对路基稳定性影响的评价。 |
