浅层物探在监测城市地质灾害中的应用

我国约有160多个城市发生不同程度的地质灾害,迫切需要查明其成因,估计其发展趋势,并提出减小灾害的方法。本文以铜陵市长江路大面积出现的地裂缝及塌陷为例,对比使用了电法、磁法、地质钻探、人工地震等方法。认为人工地震方法在喀斯特地区可以用来确定此类地质灾害的范围、趋势和找出其成因。

基于气味探测技术的矿井输送机胶带火灾监测

将气味探测技术应用于矿井输送机胶带火灾监测,以较早、准确地探测胶带火灾.煤、橡胶、机油是煤矿井下引发胶带火灾的3种主要可燃物质,气味传感器对这3种物质的受热响应实验表明,气味传感器可以在相对于火灾发生时较低的温度下监测到煤(50℃)、橡胶(65℃)、机油(110℃)受热产生的气味,并以不同温度下传感器的输出变化值(即巷道的气味变化)来判断是否发生了火灾.研究了气味传感器在井下的布置方式,认为气味传感器宜布置在气味浓度较高的混合浓度区,并通过相似理论模拟得出其间距L.

Arsenic in North Carolina: public health implications

Arsenic is a known human carcinogen and relevant environmental contaminant in drinking water systems. We set out to comprehensively examine statewide arsenic trends and identify areas of public health concern. Specifically, arsenic trends in North Carolina private wells were evaluated over an eleven-year period using the North Carolina Department of Health and Human Services database for private domestic well waters. We geocoded over 63,000 domestic well measurements by applying a novel geocoding algorithm and error validation scheme. Arsenic measurements and geographical coordinates for database entries were mapped using Geographic Information System techniques. Furthermore, we employed a Bayesian Maximum Entropy (BME) geostatistical framework, which accounts for geocoding error to better estimate arsenic values across the state and identify trends for unmonitored locations. Of the approximately 63,000 monitored wells, 7712 showed detectable arsenic concentrations that ranged between 1 and 806 μg/L. Additionally, 1436 well samples exceeded the EPA drinking water standard. We reveal counties of concern and demonstrate a historical pattern of elevated arsenic in some counties, particularly those located along the Carolina terrane (Carolina slate belt). We analyzed these data in the context of populations using private well water and identify counties for targeted monitoring, such as Stanly and Union Counties. By spatiotemporally mapping these data, our BME estimate revealed arsenic trends at unmonitored locations within counties and better predicted well concentrations when compared to the classical kriging method. This study reveals relevant information on the location of arsenic-contaminated private domestic wells in North Carolina and indicates potential areas at increased risk for adverse health outcomes.     

乌东德水库坝前段消落带生态类型划分及生态修复模式初探

采用GIS技术,根据高程、坡度、土壤类型等环境特征,将乌东德水库坝前段消落带分为18种生态类型,并完成了高程图、坡度图和土壤类型图,建立了环境特征和消落带类型的直观联系。然后根据不同的生态类型,提出了4种生态修复模式,并选择了10种植物作为生态修复物种。为其它水库消落带生态修复提供了参考依据。
