| 1. | Research on the mechanism of floor heave of roadway in deep mining 深部开采条件下巷道底鼓机理的研究 |
| 2. | On observation of moving and deforming of surface building under mining the thin coal seam 薄煤层开采条件下地面建筑物移动变形观测 |
| 3. | Located only four kilometer east suburb of longyan city , traffic is very convenient , having advantaged 4公里处,交通十分便利,具有得天独厚的资源和开采条件。 |
| 4. | According to simulated results , we can get the range of side pressure relief at the mining face , at the upper coal or the lower coal under the peculiar condition 根据模拟结果得出:特定开采条件下,上部或下部不同煤层采煤工作面侧向却压区范围。 |
| 5. | Abandoned oil field may be used to mine by the way of using pours water , the synthesis mining condition is extremely superior and has good economic efficiency 可利用中原油田废弃的油井,采用注水法采矿,综合开采条件十分优越,具有较好的经济效益。 |
| 6. | The paper sets up a groundwater three - dimensional flow model to predict the karst groundwater regime in east area of wei bei in shanxi province on the condition of exploitation 本文建立地下水三维流模型,对陕西省渭北东部的岩溶地下水开采条件下的动态进行预测。 |
| 7. | Based on the coupled model of water quality and water quality , this paper estimated the pollution condition for the water soure area , and move backward situation of handan spring 摘要采用水质水量耦合模型,对水源地的污染状况进行评价,提出不同开采条件下黑龙洞泉口的污水倒灌情况。 |
| 8. | Rough - set ( rs ) theory is applied in analyzing 36 working faces ' subsidence observation data and the dependence relation between geological mining factor and surface subsidence is obtained on the basis of these data 摘要利用粗集理论,对不同矿区36个工作面的岩移观测资料进行了分析,得到了地质开采条件和地表沈陷之间的依赖关系。 |
| 9. | Basing on this , the paper researches the mechanism of floor heave , and analyzes the effects of gravity stress , tectonic stress , the strength of surrounding rock , terrestrial heat and imbibition water on floor heave 在此基础上,研究深部开采条件下巷道底鼓发生的机理,并对自重应力、构造应力、围岩强度、地温、水对底鼓的影响进行了分析。 |
| 10. | In the condition of depletion development , its formation pressure decrease , amplitude can be 3 times of the common gas reservoirs , so the study of stress sensitivity of the reservoir rock and its effect on production performance has a great significance 在衰竭式开采条件下,其地层压力降幅可为普通气藏地层压力降幅的3倍以上,因此研究储层岩石应力敏感性及其对生产动态的影响意义重大。 |
