Urban Chemical Industrial Cluster Area Restructuring and Determinants: A Case Study of a Typical Old Chemical Industry Area Along the Yangtze River, China

China is in a transitional period between urban renewal and industrial change.In this period,the focus has been on the suburbanization of enterprises and land transformation in old industrial areas,particularly areas with chemical industries.A life cycle theoretical framework was established to develop chemical industrial zones in the context of urban expansion and land function conversion.The long-term historical processes and mechanisms that transformed a typical old chemical industry area along the Yangtze River,Yanziji Area of Nanjing City were unveiled and comparatively analyzed.The study found that the entire life cycle of the case study area was formed through the combined action of different influencing factors.Traditional industrial location factors played important roles during the rise and continuity of the chemical industry zone,while unconventional environmental regulations and government policies drove its decline and transformation.In the transformation of the old chemical zone,the renewal and redevelopment of industrial land into higher-value residential land is a key link determining the feasibility of government fund compensation and the circulation of capital.These findings demonstrate that regional control and environmental regulation play crucial roles in determining the location of polluting industries and the renewal of urban industrial areas.This research enhances the understanding of the development history and reconstruction of chemical industry clusters and plots within megacities at a finer geographic scale.

Simulation of Old Urban Residential Area Evolution Based on Complex Adaptive System

On the basis of complex adaptive system theory, this paper proposed an agent-based model of old urban residential area, in which, residents and providers are the two adaptive agents. The behaviors of residents and providers in this model are trained with back propagation and simulated with Swarm software based on environment-rules-agents interaction. This model simulates the evolution of old urban residential area and analyzes the relations between the evolution and urban management with the background of Chaozhou city. As a result, the following are obtained ： （ 1 ） Simulation without government intervention indicates the trend of housing ageing, environmental deterioration, economic depression, and social filtering-down in old urban residential area. If the development of old urban residential area is under control of developers in market, whose desire is profit maximization, and factors such as social justice, historic and culture value will be ignored. （2） If the government carries out some policies and measures which will perfectly serve their original aims, simulation reveals that old urban residential area could be adapted to environment and keep sustainable development. This conclusion emphasizes that government must act as initiator and program maker for guiding residents and other providers directly in the development of old urban residential area.

老采空区地表沉降预测合理监测模式分析

为研究老采空区沉降监测数据时间间隔对预测精度的影响,本文利用某老采空区地表沉降监测点实测沉降数据,在等时间间隔、非等时间间隔两种情况下建立两种方案、六种沉降预测模式,采用长短期记忆神经网络(LSTM)预测模型对老采空区地表沉降进行预测,以平均绝对误差(MAE)和平均绝对百分比误差(MAPE)作为评价指标,分析不同时间间隔监测数据对预测精度的影响。结果表明,在总监测时长不变的情况下,预测精度随平均监测间隔时长的增长呈先增高后降低的趋势,即并非监测间隔越短,预测精度越高,而是在相应监测间隔范围内存在预测精度最优值。研究成果可为老采空区监测方案设计及沉降预测模式提供借鉴和指导。

采卤老区“填缝补齐”钻完井工艺技术研究

为了提高矿区盐岩资源的回采率,最大限度的开采地下盐岩矿藏,在采卤老矿区“填缝补齐”布井,利用原有采卤井场改建定向对接连通生产卤井。老采区存在地下裂隙、溶腔发育等异常复杂的地下地质状况,钻完井施工中极易发生井漏、卡钻等复杂情况。本文对以上重难点问题及解决办法进行了介绍,包括井眼轨迹设计及井漏失返、冒落掉块等内容,有助于技术工作者加深对采卤矿区地层的认识,从而提高处理问题的应急能力。

工作面过斜交空巷围岩控制和支护技术研究

为了解决旧采区巷道掘进围岩稳定性控制与支护技术难题,在分析旧采区巷道围岩稳定性的基础上,开展了旧采区巷道过斜交空巷围岩运动规律数值模拟研究,分別从旧采区巷道与空巷之间夹角为15°、30°、45°、60°四种情况研究了旧采区巷道在掘进过程中空巷围岩应力分布和煤柱垂直应力分布变化规律、旧采区巷道在掘进过程中空巷围岩变形规律及不同角度三角煤柱塑性区分布规律,最后对顺槽及工作面切眼过空巷段支护参数数值进行了计算分析。结果表明:顺槽及切眼与空巷夹角越小对巷道围岩与三角煤柱应力的分布影响越大;顺槽、切眼顶板的变形量与顺槽、切眼和空巷之间夹角有关。顺槽、切眼与空巷夹角为60°时,顺槽、切眼顶板垂直位移主要集中在顺槽和空巷交界处,随着顺槽、切眼与空巷之间的夹角逐渐减小,集中区域向交界外处巷道延伸;当顺槽、切眼掘进时,由于15°夹角太小,三角煤柱太狭窄,煤柱在垂直应力的作用下破坏严重,无法进行合理的承载,距交界处12 m以上时,三角煤柱间塑性破坏较小,存在2 m以上的弹性核区,煤柱有很好的承载能力;顺槽、切眼在不同架棚棚距支护情况下围岩变形表现出不同的规律,支护越密及棚距越小,顺槽、切眼位移量越小,棚距为800 mm最为合理。研究成果为旧采区巷道围岩稳定性控制理论和围岩控制提供一种关键技术。

贵州都匀马达岭滑坡碎屑流形成泥石流特征

2006年5月18日,贵州都匀市马达岭发生滑坡,滑坡体位于马达岭沟上游采煤区,部分滑坡体滑入沟内并碰撞解体形成碎屑流堆积在沟道中上游,形成约800m长的淤积段,沟道内固体物质总量约16×104m3。滑坡后采煤区内老窑水迅速释放汇流至沟道启动沟道内物源形成泥石流运动至下游,从流通区下游逐渐淤积并少量冲出沟口,沟道内淤积长350m,堆积区体积约0.7×104m3。马达岭沟泥石流呈滑坡—碎屑流—水作用形成泥石流的连续性过程,具有典型的滑坡碎屑流形成泥石流特征。由于沟道内仍有较多物源,同时沟道内形成两处巨石淤塞形成的堰塞坝,后期强降雨作用下仍可能形成泥石流。
