我国现行“一证两权”的矿业权管理模式,将矿业权用益物权的取得、流转与行政审批许可进行捆绑,严重地制约了矿业权物权属性的发挥.矿产资源不动产登记的缺位、繁杂的矿业权行政审批和监管程序、种类繁多的矿产资源税费,增加了矿业企业经济活动的制度成本,不利于矿业企业市场活力的激发.因此,完善矿产资源产权制度,明析矿业权的物权权能;建立矿产资源不动产登记制度,保障矿业权交易安全;完善矿业权流转制度,提高市场化配置程度;推进简政放权,促进资源税制度改革,减轻矿业企业负担,激发矿业企业的市场活力,是当前矿业权管理制度改革的重点. 相似文献

找矿突破战略行动启动以来,华东地区掀起了新一轮地质找矿高潮,华东地区各省立足重点成矿区带,以深部找矿和覆盖区找矿为主攻方向,以整装勘查区为突破口,扎实推进找矿突破战略行动方案的实施,地质找矿多处取得重大进展,发现一批具有世界级储量的矿床,勘查成果超出预期,“358”第一阶段目标已基本实现。华东地区找矿突破工作虽然取得了可喜的成绩,但仍面临着一些问题和矛盾:地质勘查工作管理体制不顺、公益性与商业性工作概念不清、地勘单位体制机制改革滞后于发展需要、现有科技水平和人才培养机制不能满足找矿需求、现有矿业权管理政策不利于找矿突破战略实施的需要、地质勘查外部施工环境不顺畅、地质勘查(调查)项目资料汇交不及时、找矿突破中矿业权管理问题较多。为加强地质勘查工作、促进找矿突破工作提出几个方面的建议:进一步明确公益性队伍建设与定位;深化地勘单位体制机制改革,出台制度支持地勘单位体制机制改革;加大财政投入,保持地勘业持续稳定;改进地勘成果分配奖励办法,激发找矿积极性;进一步建立地勘人才培养使用激励机制;落实给国有地勘单位配置探矿权的优先政策,改革矿业权管理制度,促进技术与资本结合;制定地质找矿统筹规划;进一步强化勘查成果资料汇交责任;修改完善相关法律法规,优化找矿环境;出台地勘行业“走出去”工作指导意见。 相似文献

完善矿业权评估行业属地化管理的探讨 总被引:1,自引:0,他引:1
矿业权评估行业实现属地化管理,对维护国家利益和矿业权人合法权益以及预防腐败行为、完善矿业权市场机制具有重要意义。为进一步完善矿业权评估属地化管理制度,当前和今后一个时期还需要坚持国土资源部对矿业权评估机构资质的审批管理权;统一制定行业管理规章,明确矿业权管理和矿产资源保护的责任;切实加强对省级国土资源行政主管部门的监督管理,不能削弱;搭建省级国土资源行政主管部门与中国矿业权评估师协会的沟通调处机制。 相似文献

煤矿开采引起的地表移动和变形,会导致开采沉陷,一直是煤矿安全的隐患。本文选取王楼煤矿13301工作面作为研究对象,分析整理了历年来地表移动变形观测资料和观测站相关地质采矿技术条件,利用回归分析的方法进行了统计分析、曲线拟合、建立回归方程,系统性地得出地表移动值与岩移参数变化规律,求取出了矿区具体采矿技术条件下开采引起的岩层与地表移动变形参数,为矿区生产及类似地质采矿条件下岩移参数求取等提供依据。 相似文献

煤田自燃一直是煤矿生产不容忽视的问题。本文利用热红外遥感技术检测因煤火导致地面温度异常的地区,采用两种不同的遥感反演温度算法(单窗算法、基于影像的算法),使用ETM+数据并通过阈值分割法提取2010年乌尊布拉克煤田火区的温度。结果表明,两种遥感反演算法得到的地下煤火区地表温度的空间分布趋势一致,反演结果符合要求。据此对地下煤火的变化类型进行判断,并确定煤火的生成状况,从而为煤田火灾防治提供必要的决策支持。 相似文献

Abstract To investigate geological mining hazards using digital techniques such as high-resolution remote sensing, a semi-automatically geological mining hazards extraction method is proposed based on the case of the Shijiaying coal mine, located in Fangshan District, Beijing, China. In the method, the vegetation is first removed using the normalized difference vegetation index (NDVI) on the GeoEye-1 data. Then, geological mining hazards interpretation features are determined after color enhancement using principal component analysis (PCA) transformation. Bitmaps mainly covered by geological mining hazards are isolated by masking operation in the environment for visualizing images software. Next, each bitmap is classified into a two-valued imagery using support vector machine algorithm. In the two-valued imagery, 1 denotes the geological mining hazards, while 0 denotes none. Afterwards, the two-valued imagery is converted into a vector graph by corresponding functions in the ArcGIS software and no geological mining hazards regions in the vector graph are deleted manually. Finally, the correlation between factors (such as mining activity, lithology, geological structure, and slope) and geological mining hazards is analyzed using a logistic regression and a hazardous-area forecasting model is built. The results of field verification show that the accuracy of the geological mining hazards extraction method is 98.1% and the results of the hazardous-area forecasting indicate that the logistic regression is an effective model in assessing geological hazard risks and that mining activity is the main contributing factor to the hazards, while geological structure, slope, lithology, roughness of the surface, and aspect are the secondary. 相似文献

Raniganj and Jharia regions together have been for long the single largest coal supplier in India, now contributing about a quarter of the total output in the country. Numerous reasons such as improper mining techniques and policy, as well as unauthorized mining caused surface and subsurface coalfires in these areas. These coalfires burn millions of tonnes of valuable coal resources, creating severe environmental problems and posing enormous operational difficulties of mining. After first use of remote sensing as a tool to identify coalfires in 1960s, with the time, the efficiency of remote sensing to identify and monitoring coalfires has been well established by several researchers. With the knowledge of local geological setting and density sliced surface temperature image the spatial distribution of coalfires can be revealed. The present paper makes an attempt to identify temperature anomalies of the Raniganj coalbelt to locate the spatial distribution of coalfires. Landsat Thematic Mapper (TM) thermal band data was used to calculate surface temperature along with NDVI (normalized vegetation index) derived emissivity. 相似文献
