Abstract:
巷道工程的稳定是矿山生产的关键,巷道的变形破坏制约着矿山的生产,特别在高应力破碎软岩矿区,这一问题尤为严重。针对金川矿区的复杂地质构造条件,对影响巷道工程稳定的客观因素(地应力、地质构造、地下水、岩体时间流变效应等)和人为因素(开采扰动、爆破、巷道空间布置、支护方式等)进行了综合分析,提出了巷道优化布置和支护的合理建议,为矿山进行合理的巷道工程设计和施工提供科学依据。

Abstract:
地形是区域自然环境的重要组成部分,数字地形分析为人们研究地表演化过程提供了全新的技术支持。基于1∶10000比例尺DEM数据,在数字地形分析的基础上,对平朔露天煤矿区原始地貌和人工堆垫地貌的高程-平面面积、高程-地表面积和地表水系结构进行了对比研究。结果表明,人工堆垫地貌较原始地貌高度增加20~100 m;面积随着高程变化而变化,相同高程情况下人工堆垫地貌的表面积要比原始地貌大。人工堆垫地貌较原始地貌的面积在海拔1475,1425和1350 m处变化幅度大;矿区地貌景观特征发生了巨大的变化,人工堆垫地貌呈塬面水平梯田形,顶上平坦,坡面为凸形;人工堆垫过程引起原始地貌地表水系的自相似性遭破坏,人工堆垫地貌出现了环形和放射状水系,现代水系格局尚未定型。

Abstract:
针对"U"型通风工作面采空区上隅角容易积聚瓦斯,以渗流理论为基础,根据气体扩散定律和质量守恒定律,建立了顶板走向钻孔抽放采空区瓦斯流场模型。在Visual-Basic6.0平台上,利用工程软件SURFER模拟了抽放钻孔周围瓦斯压力场。结果表明,煤体自身所具备的条件和抽放瓦斯的技术条件是影响瓦斯抽放量的主要因素,采取诸多因素相结合的切实可行方案,顶板走向钻孔抽放采空区瓦斯可以取得良好的效果,在技术上是可行的。

Abstract:
A series of experimental studies were made on the effect of amide collectors with different length of carbon-chain on flotation behaviors of hemimorphite,quartz,dolomite and limonite.Meanwhile,the effect of the carbon-chain length on collecting ability of amine had been discussed.The results showed that when pH value of solution is between 9 and 11,there was the best recovery of hemimorphite,the selectivity of amine to hemimorphite is increasing with the increase of the carbon-chain length,octadecylamine has better selectivity and collecting ability to hemimorphite.

Abstract:
叶绿素浓度往往是植物营养胁迫、光合作用能力和植被发育阶段的良好指示剂。对不同程度铜胁迫下玉米的"红边"变化规律的研究表明:随着铜胁迫程度的不断加深,"红边"波长位置有规律地沿着波长轴不断向蓝光方向移动;叶绿素浓度与其"红边"波长位置之间有着极强的线性相关关系。在分析的基础上,建立了基于"红边"波长位置的叶绿素浓度回归模型,其复相关系数(R2)达到0.884为植被受重金属污染时开展高光谱遥感监测研究打下了坚实的基础。
