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
通過大規模的現場試驗和爆破震動測試，得出了銅山口銅礦露天采場各區段的優化爆破參數以及生產爆破產生的地震波在東幫的傳播規律，在此基礎上提出了降震措施並得出如下主要結論： 1In order to break through the traditional technology and the conception of equipment design, suggest to use bunchy phase deep hole or big diameter deep hole in laneway to realize the exploding of high step on opencast working ; digging with big contain forklift to realize the continuous transportation of dragline - mobile convolution crusher - belt transportation machine, therefore form a new technology system that be propitious to increase collectivity technique and economic benefit
為突破基於常規工藝和設備配套的設計理念，推薦採用束狀階段深孔或在巷道中採用大直徑深孔的方法實現露天開採的高臺階穿爆作業；採用大斗容索鏟下挖作業實現自工作面開始的索斗鏟移動式旋迴破碎機帶式輸送機的連續運輸工藝，從而形成有利於提高露天開采設計總體技術經濟效果的新的工藝技術系統。Considering cast blasting was to be carried in one internal coal surface mine, the cast blasting parameters, pre - splitting blast parameters, types of explosive and construction of charge were studied based on overseas examples
摘要針對國內大型露天煤礦要採用高臺階拋擲爆破技術，根據國外的事例經驗，詳細研究了高臺階拋擲爆破參數、預裂爆破參數、炸藥類型和裝藥結構。In order to decrease the size of fragmentation and reduce blasting vibration effects on the stability of eastern open pit slope of tongshankou copper mine < this work involved two steps. first of all, based on the experiment in laboratory, this paper presented the optimum blasting parameters and applied it in practice
為降低銅山口礦露天采場生產爆破的大塊率和地震波振動強度，保證采場東幫陡邊坡的穩定，本文在對國內外大量文獻綜合調研的基礎上，首先採用正交設計對現場爆破參數進行了室內模型實驗，得出優化的模型爆破參數后又應用於生產。Based on a directional cast linear charge blasting in meng jia gou mine at 17, 9, 2003, the measurement and results of blasting vibration are fully analyzed
