博士生杨滨滨在Mine Water and the Environment发表论文

杨滨滨2017年5月在期刊《Mine Water and the Environment》上发表了题目“Risk Assessment of Water Inrush in an Underground Coal Mine Based on GIS and Fuzzy Set Theory”的学术论文,该期主要刊载采矿工程中矿井水问题的评估、预测、预防或控制及其对环境的影响等方面的内容。IF=1.278。

论文摘要:基于地理信息系统(GIS)和模糊集理论提出了一种煤层底板突水危险评估方法。采用分形法量化断层特征,模糊集方法识别控制煤层底板突水的地质和水文地质主控因素。采用GIS方法确定隶属度,Shannon信息熵法确定主控因素权重,最大隶属度原则评价底板突水风险水平。通过河南省永城陈四楼煤矿2517工作面工程案例验证了评估方法可行性,该工作面煤层底板含水层经过注浆加固。2014年11月至2016年4月数据显示2517综采工作面突水危险性低;实际开采过程亦没有发生底板突水。该方法能够量化地质及采矿等影响,为一种系统评价煤层底板突水危险的工具。

Abstract:A systematic method was developed to evaluate the risk of water inrush through a coal seam floor using the geographic information system (GIS) and the fuzzy set theory. The main geological and hydrogeological indicators that control water inrush were first considered using a fuzzy mathematics approach, in which fractal analysis was carried out to quantify the fault’s characteristics. The degree of membership was determined using GIS, the weight of every factor was considered by calculating the entropy in accordance with Shannon’s information entropy theory, and the level of risk of the evaluated object was derived using the maximum membership principle. The approach was validated by a case study at the Chensilou mine in Henan Province, China, where the aquifers that underlie an exploitable coal seam, II2, were made impermeable by grouting. Data from Nov. 2014 to April 2016 shows that the risk of water inrush was reduced in Panel 2517 of the II2 coal seam, that there were no serious disturbances in this panel and no groundwater inrush through the floor. This method can be a powerful tool for systematically assessing the risk of water inrush through the floor, since the influence of several factors can be quantitatively considered in accordance with the geological and mining conditions.
