三级监察网络——煤矿违法开采的“克星”     

刘金红顾振营  王建泽 《河南国土资源》2005,(7):34-34

面对超层越界、无证采矿和以采代探等违法采矿行为屡禁不止这一“顽疾”，禹州市国土资源局主动探索，推陈出新，走出了一条行之有效的执法监察新路子，即实行局各资源所(站)、测绘大队和执法大队三级监察网络，避免了违法行为排查的被动性、巡查的盲目性、查处的滞后性，做到了有计划、有重点、早发现、早制止、早处理，将一大批矿业违法活动消灭在萌芽状态，煤矿违法开采活动数量明显减少。  相似文献

DISASTER ANALYSIS AND COUNTERMEASURES OF LAND SUBSIDENCE CAUSED BY COAL CUTTING IN CHINA     

YANGYong-liang SHITong-guang JLANGLU-guang LIYue 《中国地理科学(英文版)》2003,13(2):130-133

In recent years, many coal-producing countries have paid great attention to the land subsidence causedby coal cutting. In China, because of the dense population in coalfield areas, the land subsidence hazard is more seri-ous. After a brief analysis on the mechanism of land subsidence, this paper gives a comprehensive and systematical ac-count on all kinds of hazards caused by the land subsidence in China. The study shows that land subsidence has endan-gered land, buildings, traffic and communication lines, dykes and dams. It also causes damage to ecological and socialenvironment. In order to lessen the hazard of land subsidence, preventive measures should be taken to reduce the col-lapse amount, such as extraction with stowing, banded mining system, succession and coordination mining system, orhigh-pressure mudflow between rock strata. Measures of reinforcing or moving certain buildings should also be taken toreduce the destructive degree. In order to harness the subsidence land and bring them under control for fanning, mea-sures should be taken such as filling with spoil or fine breeze, excavating the deeper and covering the shallower land.  相似文献   

广西小平阳岩溶区地裂缝形成因素分析     

张骏  卢玉东  孙建中  范文 《地球科学与环境学报》1996,(4)

８０年代以来，广西小平阳岩溶区出现了大量的地裂缝。通过调查研究．这些地裂缝的形成是受多种因素控制的．其中包括构造、土体性质、水的作用、地形地貌、气候及植被等因素。在上述因素中．构造是主导因素，上体性质是基础因素．其它则为诱发因素，也是因地质环境要素变化所引起的因素。主导因素是通过诱发因素起作用的．并最终通过土体性质因素导致产土地裂缝。  相似文献

Study on numerical simulation to water lowering in an open coal mine digging     

Yanjun ZHANG Fenglong ZHANG Full QI Fuquan NI 《东北亚地学研究》2006,9(2):199-203

In view of the situation of excavation of open coal mine for the underground water disaster,we should carry out simulation studies for the numerical value of the water lowering project and improve the accuracy and the level of the water lowering project.On the basis of the hydrological geological conditions of certain open mine digging,a more reasonable seepage numerical model was built according to MODFLOW.It was simulated in advance that the process of the confined water level descending with the time,and combining with the actual observations to test the correctness of the model.The calculation showed that the results coincided well with the results of actual measurement.Based on this,different water lowering numerical simulations were built for the open coal mine digging.It could be simulated and forecast that the changes of the groundwater level in drainage process within and outside the mine pit,and it was quantitatively assessed that the possible water lowering result of the opencast water drainage process,which provide an important basis for the actual water lowering project and the possible project disposal.  相似文献
