准格尔煤田储层孔隙—割理系统非均质性及其与煤岩组成之间的关系

从野外和矿井观察统计、光学显微镜观测以及压汞、低温液氮吸附、渗透率实验室测试三个研究层次入手，对影响煤层渗透率各向异性的岩石学因素进行了分析。结果表明：在煤级相似的条件下，煤的“基质渗透性”似乎主要取决于煤层的物质组成；若煤层物质组成相似，则同一地区不同煤层或不同地区同一煤层之间渗透性的差异可能主要起因于受割理发育程度所控制的“割理渗透性”；煤层中不同煤岩类型条带的空间分布特征是决定煤层渗透性各向异性的一个重要因素。     

塔北—南天山地区震旦—奥陶纪盆 山构造演化及其与油气关系

震旦—奥陶纪时期塔北与南天山地区在“新疆古克拉通”的基础上经历了一个伸展、裂离和挤压、聚合的完整旋回。该区由南向北大致可分为３个近于平行的与伸展作用有关的构造区带：（１）南库鲁克塔格裂陷槽—满加尔克拉通边缘坳陷—塔里木克拉通内坳陷；（２）北库鲁克塔格—铁门关—老虎台隆起带；（３）南天山洋盆。该时期的构造演化可大致分为３个阶段：（１）震旦纪伸展 裂陷阶段；（２）寒武纪—早奥陶世伸展 裂离阶段；（３）中—晚奥陶世挤压 聚合阶段。具有伸展盆地性质的满加尔克拉通边缘坳陷是该区的主力生油坳陷，其热演化程度高，位于其北侧的继承性古隆起及斜坡是主要的油气运移指向和聚集场所。     

应用人工神经网络解释煤层厚度

本文介绍了人工神经网络解释煤层厚度的方法，为直接利用煤田地震资料确定煤层厚度提供了一种新的途径。利用煤层厚度与煤层反射波动力学特征参数之间的非线性关系，用人工神经网络进行定量描述，便可根据地震资料求出煤层厚度。     

结构阻尼识别中的目标函数问题

本文以三对共六个小型单层钢框架的弹性动力试验和弹塑性动力－静力对比伙依据，分别以结构的绝对最大位移反应ＭＤ，位移平方和反应ＳＳＤ总滞回耗能ＥＨ作为等效目标，对结构阻尼识别中的目标函数选取问题进行了讨论。     

山西口泉断裂与大同侏罗纪煤田的关系

山西口泉断裂是一条规模大，活动期长的大断裂，它构成了云岗断坳与桑干河新裂陷的构造单元界限，同时又是大同侏罗纪煤田的东部边界，一般认为，这一大型基底断裂的形成和演化对煤田地质构造的发育具有重要的控制作用。本文对这一构造的形成机制和演化历史进行了分析研究，阐述了口泉断裂的青磁窑断层对大同侏罗纪煤田地质构造的展布规律和构造特征的控制关系。     

An historical review of landslide research in the South Wales coalfield

Summary The areal density of landslides in the coalfield of South Wales is one of the highest in the UK. During the past 100 years landsliding has had considerable impact, causing structural damage and loss of life. Most of the landslides were initiated under periglacial conditions but many became reactivated due to the activities of humans, particularly during the late 19 th century when widespread urban and industrial development commenced in the Welsh valleys. A number of the area's larger landslides are first-time slides which occurred during the past 100 years. This paper sets out to chart the history of landslide research in the coalfield, which began through work by mining engineers.

A comparison of rock mass disturbance in TBM and drill and blast drivages at the Donkin Mine,Nova Scotia

Summary The initial phase of the Donkin-Morien project involves the driving of two parallel tunnels through an interbedded sequence of coal measures strata to intersect the Harbour Seam which lies approximately 3.5 km offshore. The No. 2 tunnel was driven a total distance of 3579 m using a 7.6 m diameter full face shielded Lovat TBM and supported by steel ring beams. The No. 3 tunnel was initially driven a distance of 1027 m using conventional drill and blast methods (7.6 m wide by 5.3 m high with a uniradial arch and supported by rock bolts and shotcrete). The TBM was subsequently used to complete the drivage of the No. 3 tunnel to the Harbour Seam.Both the No. 2 and No. 3 tunnels followed a thick sandstone unit at a grade of –20% for the first 900 m. This provided an opportunity to compare the rock mass disturbance resulting from two different excavation methods. A programme of field and laboratory measurements was therefore undertaken, which included: the use of a borehole dilatometer to determinein situ rock modulus,in situ gas permeability testing, seismic reflection surveys on the tunnel walls, and the laboratory testing of core samples.The paper examines the four different techniques used and compares the results obtained.     

中国东北部晚中生代断陷盆地模式在松辽深部煤成气预测中的可能应用

经地震探测和地质分析,松辽深部晚中生代断陷盆地与其周围地区J_3—K_1的断陷盆地在地质结构和成盆期均具有相似性,同属东北亚晚中生代断陷盆地系。作者认为,应用其周围同类型断陷盆地模式对松辽深部煤成气远景的预测和生油潜力的判断具有重要价值,同样也适用于深埋于下辽河第三纪坳陷之下的晚中生代盆地成气远景的预测。
