| 摘 要： | 随着内蒙古自治区二连盆地群早白垩世陆相沉积煤田的大规模勘查和开发建设,一些大(特)型露天煤矿的边坡工程地质勘察及稳定性分析评价工作也已陆续展开,但由于各勘察施工单位的工作方法不尽一致,给边坡岩体的稳定性评价带来了一定的影响。以盆地群内的胜利煤田东二号露天煤矿、白音华煤田一号露天煤矿工程地质勘察实践为例,对下白垩统巴彦花群煤系软岩边坡工程地质勘察中的软岩强度的界定、岩心采样方法的选择、数字测井成果在解释软弱(夹)层中的应用、钻孔波速测试方法的应用和边坡稳定性随含水率变化的敏感度分析5个方面进行了详细论述,并提出了相应的划分标准与技术方法。此结果可使盆地群中露天煤矿边坡工程地质勘察工作更加合理。

| Abstract: | Along with extensive exploration and exploitation of Early Cretaceous limnic coalfields in the Erenhot basins, IMAR, slope engineering geological exploration of some lager （extra large） surface eoalmines were also deployed. But because of operating methods of various exploration operation units are not completely identical, resulted in certain extent differences on slope rock mass stability assessment. To take the engineering geological exploration practices in the Shengli coalfield east No.2 and Baiyinhua No.1 surface eoalmines as examples, amply dissertated 5 aspects of soft rock strength definition, rock core sampling method selection, application of digital well logging results in soft rock bed （parting） interpretation, borehole wave velocity determining method and susceptibility analysis on slope stability varying in company with specific moisture content and put forward corresponding partition standards and technical methods in Lower Cretaceous Bayanhua Group coal measures soft rock slope engineering geological exploration. The result can make surface coalmine slope engineering geological exploration tasks in the basins much more in reason. |
