跟类星体红移宇宙学解释相符合的证据

分析类星体吸收线红移和发射线红移的特征。我们从Hewitt和Burbidge（1993）的星表中选择了吸收线红称和发射线红移都同时提供的类星体，得到了包含401个对象的样本。这是至今对类星体红移研究的最大样本。我们从吸收线红移和发射线红移之间的关系图发现绝大多数（93．6％）对象的吸收线红移都小于相应的发射线红移。这个结论人们在20世纪70年代已经从很小的类星体样本（样本大小50左右）中得到。本文进一步支持了这个结论。它表明类星体红移确实是距离的指示器。这跟宇宙学对类星体红移的解释是一致的。     

红阳煤田石炭-二叠纪含煤地层的沉积特征

红阳煤田含煤地层太原组与山西组,是一套典型的“海陆交互相”沉积。依据剖面上沉积相序列变化特点,可划分为14个沉积旋回,每个沉积旋回均含有一层煤。有二种聚煤环境:一是海水退出潮坪后形成的泥炭沼泽聚积的煤层;二是扇三角洲平原形成的泥炭沼泽聚积的煤层。     

三级监察网络——煤矿违法开采的“克星”

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。     

广西省右江流域之“红锑”矿

红锑即养化锑,土人因其表面多显红棕色,故统名之曰‘红锑’此种红棕色,实为由铁质渲染而成。此矿在桂省西部左江流域之分布甚广,计有田东、田阳、天保、靖西,镇结、向都、万罔、平治、万承、龙茗、养利等县,其年产量之最高数字,

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

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.

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

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.
