Examples
- Research on safely mining key technology of coalbed in zone of weathering and oxidation under thick loose bed
厚松散层下风氧化带内煤层安全开采关键技术的研究 - The extreme effects of sand mining on local deformation of riverbed and evolution of river stretch in typical river sections such as straight river section , river bend and river fork are experimentally studied in micro - scale loose bed hydraulic model
摘要采用微尺度动床河工模型试验的方法研究了在顺直、弯道与分汊等典型河道不同部位进行大规模采砂对河床局部变形及对河段变形的极限影响。 - With the rapidly development of minefield and the rapidly increase of coal output , the excavation scope and depth will extremely rise , the excavation work is under the overlying by the thin rock strata , and under the thick loose bed , the population in mine field will be more and more , the relevant basic industries will also develop rapidly . the mines will discharge more water from the underground , and the production and living will also consume more water . so the original water resource balance system in the minefield will be broken , the ecological environment formed by the nature will be destroyed in some degree
随着矿区迅速发展而煤炭产量的快速增长，既定在薄基岩厚松散层下的神东煤田开采范围和深度势必急剧增大，相应的人口也增加，与其相匹配的其它基础工业一并迅猛发展，导致矿井外排水和生产生活用水直线猛增，这一系列生产和生活巨量用水必然会打破矿区原始的水资源平衡体系，不同程度的破坏自然形成的脆弱的生态环境。
