Research on Combined Support Technology of High Convex Strip-bolting for Deep Soft Rock Roadway

タイトル: Research on Combined Support Technology of High Convex Strip-bolting for Deep Soft Rock Roadway

著者: ZOU, Zhengsheng; LI, Zhiping; LUO, Pingping; LI, Lifeng; DU, Jiaqing

抄録: Based on the systematic analysis of mechanical characteristics for deep roadway excavated in soft strata, the high convex strip-bolting support technology was put forward, and a numerical analysiswas carried out by FLAC3D. The process of general bolting support and high convex strip-bolting support of deep soft rock roadway were simulated. The results indicate that the convex bed of strip-band can adapt to large deformation of high pre-stressed bolting, and the high strength and highrigidity of strip can bear large axial force and moment of flexion. In addition, bolting and anchoring combined support can control the deformation of rock masses by transferring the strength of deepstrata, and bolt-grouting can form stress-relief region in deep and generates high strength invert arch at shallow which can afford some support resistances. A case study is also presented and the results offield measurement show that the new support system is suitable for roadways excavated in weak rocks.

Research on the Degradation of Residual Coal and Gangue in the Mine by the Enrichment of Biogas

タイトル: Research on the Degradation of Residual Coal and Gangue in the Mine by the Enrichment of Biogas

著者: DENG, Yinsheng; TANG, Min; HUANG, Yan; SHEN, Zhe

抄録: In this paper, simulation study is carried out focusing on both enrichment of biogas and regulating the value of C/N, which are the effect on the degradation of residual coal and gangue by enrichhment of biogas. The paper comes to the conclusions that : (1) Microorganisms in bacterial liquid is rich through enrichment of biogas, and results show that it is feasible according to degradation effect.(2)Application of nitrogen provides ample sources of nitrogen (NH4+) for microorganisms. The available nitrogen (NH4+) content increases, and microorganisms grow well, which are benefit fromanaerobic fermentation. (3) The reduction rate of organic matter is basically consistent with gas production, furthermore the quantity of microorganisms determines the utilization degree of organicmatter. (4) Considering both gas production and organic matter content, organic matter in gangue is indeed degraded by microorganisms.

Research in Environmental Geological Disasters and Prevention Countermeasures of Mountainous Area Highway

タイトル: Research in Environmental Geological Disasters and Prevention Countermeasures of Mountainous Area Highway

著者: LI, Xian-min; LI, Qiang; LIANG, Yan-hui; WANG, Yong-he

抄録: In this paper the natural environment geology disasters of mountainous area highway are firstly elaborated, and such geological disasters and their origin as collapse, landslide, mud fluid, Karst,flood damage, special soil, earthquakes and so on is analyzed emphatically. At the same time, such environment geological disasters easily caused by people as roadbed of filling and cutting, constructing bridge and tunnel, changing water course, and so on, are elaborated in detail duringconstructing mountainous area highway. In view of the construction and operation of mountainous area highway faced by the natural and artificial environment geological disaster, it is proposed thatforecasting and preventing geological disaster and effectively developing environmental protection countermeasures.

Investigation of Cross Border Environmental Management and Consciousness at the Local Level: Power Plant Development within a Confined International Air Shed

タイトル: Investigation of Cross Border Environmental Management and Consciousness at the Local Level: Power Plant Development within a Confined International Air Shed

著者: BUCKLEY, Patrick; BELEC, John

抄録: Localized cross-border management of environmental issues is a growing trend. This paper focuses on a pair of nested questions regarding such management using a Delphi Methodology applied to apanel of local decision makers along the United States – Canada border. First, in response to the past threat of overstressing the shared air-shed is a trans-border consensus emerging among decisionmakers? Second, if true, might Cross-Border theory and the applied model of the International Watershed Initiative provide insight into how cross-border management might evolve? The study answers each of these affirmatively. However, when the panel is asked if a similar consensus existsacross the general public of the transnational - region, panelists are split. Half clearly in the affirmative and half in disagreement, but the bifurcation is not based on nationality. Clearly this isthe next area for investigation.
