采掘诱发地震的成因及对策

根据煤或岩体的赋存特征及采动后的受力特点，将采矿及掘进等工程进行过程中诱发的地震灾害分为三类，即完整煤岩体受压应力作用的失稳、顶底板受拉应力型地震及断层走滑受剪型诱发地震。文章在分别分析其成因的基础上，研究了采矿诱发三种类型地震的发生条件，提出了防治发生诱发地震的对策。

菝葜水煎液抗炎活性的实验研究

目的：探讨菝葜水煎液的抗炎活性。方法：利用巴豆油合剂致小鼠耳肿胀、醋酸致小鼠胸膜炎和皮下植入棉球致小鼠生长肉芽等3个实验模型研究菝葜水煎液的抗炎活性。结果：菝葜水煎液对巴豆油合剂引起的小鼠耳肿胀具有显著的抑制作用，而对醋酸引起的小鼠胸膜炎和皮下棉球引起的小鼠肉芽肿则仅有一定的抑制作用。结论：菝葜水煎液具有一定的抗炎活性。     

陕西泾阳4.8级地震前后重力变化与断裂活动

本文对泾阳Ms4．8级地震前后陕西关中地区流动重力观测资料和有关断裂垂直形变资料进行了分析研究。结果表明：①波速比高值区很可能存在地下深部地幔物质的入侵，由此引发地震和重力场的显著下降；②用震源机制解和GPS所作的运动矢量图可以较好地解释泾阳地震前后重力场时空演化特征及有关断裂活动——其变化是北西向剪切应力带作用的结果．     

关于综放开采技术安全问题的几点认识

本文从放顶煤开采的一次采高大、上覆岩层的活动范围大、破碎顶煤的存在等基本特征出发,论述了关于放顶煤开采中瓦斯、顶板和冲击地压等安全问题.放顶煤开采对有些安全问题可以缓解,比如工作面的瓦斯突出.但是也可能诱发一些安全问题,如坚硬顶板对支架的冲击、采空区垮落岩石的撞击与摩擦诱发瓦斯事故等.在放顶煤大面积推广应用的同时,更应重视其相应的安全问题的系统研究与解决.

Improving Operational Planning and Management of National Parks in Turkey: A Case Study

The purpose this study was to improve operational planning and management of national parks in Turkey to balance conservation use and sustainable management. Souksu National Park (SNP) was chosen as the study area. The data were obtained from interviews of 182 visitor groups (in total, 819 people) and analyzed using correlation, factor, discriminant, and regression analyses. It was found that the most important factors affecting operational planning and management of SNP are (1) travel cost, (2) visitor welfare level, (3) intensity of use, (4) size of visitor group, (5) type of recreational demand. The main source of visitors to SNP is from a zone within a 0–90-km radius. This region comprised 53.85% of total visitors to the park. The capital of Turkey (Ankara) is the most important source of visitors from within this zone. The optimum activity mix in SNP is also determined. Picnicking, viewing the scenery, and nature walks or trekking comprised the main uses of the park. It is anticipated that these findings will help to improve operational planning and sustainable management of the national park and the environment.     

The challenges of sustainability in mining regions: The coal mining region of Santa Catarina, Brazil

Throughout history, mining communities have invariably found themselves striving for a good quality of life and a long‐term future. In the 21st century, problems of maintaining the economic vitality of mining regions are now compounded by concerns about the biophysical integrity of the local environment. In regions of the world where the economic viability of the resource is marginal and achieving a reasonable quality of life is a daily struggle, sustainable mining may seem to be a dubious prospect at best. Yet the twin imperatives of global political forces and burgeoning environmental concerns are requiring industry, governments and other interests to re‐conceptualize the way in which mining takes place in communities. Although mining itself may not be seen as an industry that contributes to the achievement of environmental objectives, it could — with careful planning — be used as a tool to foster a more sustainable and healthier community. This argument is considered in the context of the coal mining region of Santa Catarina, Brazil.     

The dynamics of artisanal and small-scale mining reform

Artisanal and small‐scale mining are activities that have long been established in many developing countries, employing millions of people globally, either directly or in affiliated industries. Also, such activities are deplored for their adverse environmental impacts and their general avoidance of governments, tax collectors and other regulators. Decades of work have gone into addressing these problems, but with limited overall progress in evidence. Going back to some of the key dynamic relationships involved in artisanal mining and small‐scale mining, the need for policy reform that gives consistent and effective incentives is argued to be the foundation on which other discussions about environmental protection, sustainability and livelihoods can be built.
