刘清泉副教授受聘担任SCI期刊Geofluids的academic editor一职

近日，应Hindawi出版社邀请，刘清泉副教授受邀担任sci期刊《Geofluids》academic editor一职，协助AD处理煤矿瓦斯灾害相关的稿件。

Geofluids is part of a partnership between Wiley and Hindawi and is now fully open access. Geofluids will remain a Wiley title but will be published and hosted by Hindawi, and will benefit from Hindawi’s experience and expertise in publishing open access titles. 

Geofluids provides an international forum for original research into the role of fluids in mineralogical chemical and structural evolution of the Earth’s crust. Its explicit aim is to disseminate ideas across the range of sub-disciplines in which Geofluids research is carried out. To this end authors will be encouraged to stress the transdisciplinary relevance of their research and to make their work as accessible as possible to readers from other sub-disciplines. Geofluids emphasizes both chemical and physical aspects of subsurface fluids throughout the Earth’s crust (although excluding silicate melts). Geofluids spans studies of groundwater terrestrial or submarine geothermal fluids basinal brines petroleum metamorphic waters or magmatic fluids but requires relevance to processes that are significant on a geological time scale. Authors are encouraged to submit articles that describe theoretical or observational studies explore the geologic geochemical or geophysical attributes of subsurface fluids quantify the geologic controls on permeability geochemical transport and heat transport or document applied aspects of crustal fluid behaviour. Examples of appropriate areas for articles include but are not restricted to: composition and origins of Geofluids hydrodynamics of sedimentary basins; role of regional groundwater flow in geologic processes chemical or physical behaviour of Geofluids in porous or fractured rocks palaeohydrology of flow regimes as inferred from isotope systematics and fluid inclusion studies relations between past or present fluid flow and geothermics of the Earth’s crust structural and seismic controls on deep fluid migration the role of fluids in crustal deformation role of groundwater chemistry in landscape evolution soil development and evaporite formation mechanisms of petroleum generation migration and the interaction of hydrocarbons with groundwater reactive flow in rock media fluid flow heat transport and chemical metasomatism associated with hydrothermal ores geochemistry of dissolution transport and precipitation by fluids mathematical and experimental studies of geofluid migration fluid flow accompanying metamorphism or magmatic crystallisation fluid pressure regimes in the crust.

工作室获得一项发明专利授权

近日，煤矿智慧瓦斯治理工作室的一项发明“一种煤层冲孔形状的测定装置及其使用方法”获得授权。

该专利在平煤八矿水力造穴项目的工业实践中提出了一套完整系统的测定煤层水力冲孔形状装置，并说明了配套的使用方法。在2019年7月提交申请，2020年1月答复专利局审查意见，于2020年2月获得授权。

专利背景

水力冲孔是通过高压水射流在煤层造穴产生孔洞，以此达到卸压增透的目的。孔洞的大小与形状直接影响着卸压范围和效果，因此定量的考察冲孔孔洞形状尤为重要。现有技术无法准确定量的测定还原煤层水力冲孔造穴成孔的形状，常用的方法有钻孔窥视仪观察和钻孔出煤量计算反推。钻孔出煤量计算反推法假设孔洞为圆柱形不符合实际情况。两种方法都仅凭经验无法准确判断孔洞形状及边界。

针对上述存在的技术不足，本专利提供了一种煤层冲孔形状的测定装置，通过旋转的激光测距仪来测量其到周围孔壁的距离，能够测量不规则的孔洞形状，使用简单且较为精准。

本专利已获得企业基金资助，进一步加快了现场实践与转化，具有广阔的应用前景。

学术论文 Numerical assessment of the critical factors in determining coal seam permeability based on the field data 录用

经过一年多的学习、研究、撰写与修改，论文 Numerical assessment of the critical factors in determining coal seam permeability based on the field data 近日收到期刊 Journal of Natural Gas Science and Engineering 录用通知。该期刊在工程领域属于JCR一区，5年综合影响因子3.909。

论文简介：径向流量法是我国广泛应用的煤层透气性系数现场测定方法。然而该方法的理论基础是单孔介质的瓦斯流动模型，并且以抛物线方程代替朗格缪尔方程和理想气体状态定律表示煤层中的瓦斯含量。这种简化会对径向流量法的精度产生影响。本文的目的是研究该方法对不同的朗缪尔体积、朗缪尔压力和基质尺度煤层测量渗透率的准确性。（点击查看课题详细介绍）
