| 1. | Three dimensional numerical simulation for explosion cavity forming of linear charge in soil 条形装药土中爆炸成腔的三维数值模拟 |
| 2. | The paper outlines the development of linear charge blasting techniques and puts forward the necessity of researching characteristics of blasting vibration on linear charge 摘要简要介绍了条形药包的发展现状,指出了条形药包大爆破地震特性研究的必要性。 |
| 3. | D ) . puts forward stress wave research method when the linear charge blasting . it regarded column stress wave as cylinder stress wave , end stress wave as spherical wave D )提出了将条形药包柱部应力波当作柱面波、端部应力波当作球面波处理的应力波研究方法。 |
| 4. | 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 结合2003年9月16日在首钢孟家沟铁矿成功进行的一次条形药包露天矿揭顶剥离松动大爆破,对爆破地震的测试及结果进行了全面分析。 |
| 5. | After this , according to the difference between practice and perfect condition , the paper establish the stress attenuation formula on the radical direction under linear charge blasting 随后对理想方程进行了修正,建立了条形药包爆破径向应力理论衰减方程。并利用已有试验结果对所获得的径向应力衰减方程进行了验证。 |
| 6. | Acquires radial stress attenuating formula of the spherical charge and cylindrical charge in completely elastic medium and the radial and axis stress attenuating formula of linear charge in the rock 获得了完全弹性介质条件下,球药包和条形药包径向应力衰减方程和矿岩介质条件下条形药包径向和端部轴向应力衰减方程。 |
| 7. | On the foundation , the perfect stress attenuation formula in linear charge blasting has been reduced by the principle formula of blasting attracted face of the paper and the stress attenuation formula of spherical charge 在此基础上,根据本文建立的爆破吸引面本构方程和球药包应力公式,建立了理想的条形药包爆破径向应力衰减方程。 |
| 8. | It also has been validated by the test result . on the basis of reduced stress attenuation formula , the paper elicit theoretical calculation expressions of jam lengths in hole blasting and space between charges in linear charge blasting . linear charge blasting at the net of highway to zhuhai aerodrome and the hole blasting at underground stope in gaofen mining company have been design by the expressions 根据建立的条形药包爆破径向应力衰减方程,得出了浅孔爆破堵塞长度和条形硐室药包爆破药室间距理论计算公式;按推导的计算式设计了珠海西区机场路垭口条形药包爆破和高峰矿业有限责任公司地下采场浅孔爆破。 |
| 9. | It make the principle formula become simpler and more practical . by the attenuation regulation and distributing character of stress wave under the linear charge blasting , the paper bring forward the idea that the columniation stress wave can be regarded as cylinder stress wave , the end stress wave as spherical wave . the perfect stress attenuation formula in radical direction is established in complete elastic medium 根据条形药包爆破应力波分布特征及衰减规律,提出了可将条形药包爆破柱部应力波当作柱面波、端部应力波当作球面波处理的研究方法:建立了理想的完全弹性介质中球药包和条形药包爆破径向应力衰减方程。 |
