| 1. | Simulating test study in shallow seam mining under thick soil of the earth ' s surface 地表厚土层浅埋煤层开采模拟实验研究 |
| 2. | Study on reclamation and filling of ground subsidence area in thick soil mining area 西部巨厚黄土矿区采动塌陷区复垦充填研究 |
| 3. | The hydrogeological and engineering geological properties of thick soil layers in taiping coal mine 太平煤矿深厚土层的水文地质工程地质性质 |
| 4. | Evaluation and application to the prediction model indicate that the problem for predicting subsidence of thick soil lager is properly solved 对预计模型的评价及应用表明,该方法可以较好地解决厚黄土层矿区地表移动的预计问题。 |
| 5. | The strata behavior rule of longwall face with individual props in shallowly buried coal seam covered with thick soil was summarized 实验和观测表明,尽管其上覆岩层的力学强度比较小,煤层埋深浅,但工作面初次来压步距大,矿山压力显现剧烈,周期来压台阶下沉量大。 |
| 6. | As for toluene , it was shown that the cumulative mass discharged from the gcl composite liner was several orders of magnitude greater than that from composite liners having a thicker soil liner 研究发现对于挥发性有机化合物甲苯,土工膜和gcl组成的复合衬里的浸出液总量要比土工膜和较厚粘土衬里组成的复合衬里大好几个量级。 |
| 7. | In accordance with peculiarity of earth ' s surface being covered by thick soil layer , the stratum in north - west mining area , are classed as rock layer and soil layer , and the mathematic model of predicting surface movement is established according to the stochastic medium theory , the method for solving mathematic model and setting - out the parameters in prediction are developed 摘要针对西北矿区地表为巨厚黄土层的特性,将上覆地层分为岩层和土层两种不同介质,应用随机介质理论建立此类矿区地表移动预计的数学模型,并提出模型的解算方法及预计参数的确定方法。 |
