Abstract:
巷道工程的穩定是礦山生產的關鍵,巷道的變形破壞制約著礦山的生產,特別在高應力破碎軟巖礦區,這一問題尤為嚴重。針對金川礦區的復雜地質構造條件,對影響巷道工程穩定的客觀因素(地應力、地質構造、地下水、巖體時間流變效應等)和人為因素(開采擾動、爆破、巷道空間布置、支護方式等)進行了綜合分析,提出了巷道優化布置和支護的合理建議,為礦山進行合理的巷道工程設計和施工提供科學依據。

Abstract:
地形是區域自然環境的重要組成部分,數字地形分析為人們研究地表演化過程提供了全新的技術支持?；?∶10000比例尺DEM數據,在數字地形分析的基礎上,對平朔露天煤礦區原始地貌和人工堆墊地貌的高程-平面面積、高程-地表面積和地表水系結構進行了對比研究。結果表明,人工堆墊地貌較原始地貌高度增加20~100 m;面積隨著高程變化而變化,相同高程情況下人工堆墊地貌的表面積要比原始地貌大。人工堆墊地貌較原始地貌的面積在海拔1475,1425和1350 m處變化幅度大;礦區地貌景觀特征發生了巨大的變化,人工堆墊地貌呈塬面水平梯田形,頂上平坦,坡面為凸形;人工堆墊過程引起原始地貌地表水系的自相似性遭破壞,人工堆墊地貌出現了環形和放射狀水系,現代水系格局尚未定型。

Abstract:
針對"U"型通風工作面采空區上隅角容易積聚瓦斯,以滲流理論為基礎,根據氣體擴散定律和質量守恒定律,建立了頂板走向鉆孔抽放采空區瓦斯流場模型。在Visual-Basic6.0平臺上,利用工程軟件SURFER模擬了抽放鉆孔周圍瓦斯壓力場。結果表明,煤體自身所具備的條件和抽放瓦斯的技術條件是影響瓦斯抽放量的主要因素,采取諸多因素相結合的切實可行方案,頂板走向鉆孔抽放采空區瓦斯可以取得良好的效果,在技術上是可行的。

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:
葉綠素濃度往往是植物營養脅迫、光合作用能力和植被發育階段的良好指示劑。對不同程度銅脅迫下玉米的"紅邊"變化規律的研究表明:隨著銅脅迫程度的不斷加深,"紅邊"波長位置有規律地沿著波長軸不斷向藍光方向移動;葉綠素濃度與其"紅邊"波長位置之間有著極強的線性相關關系。在分析的基礎上,建立了基于"紅邊"波長位置的葉綠素濃度回歸模型,其復相關系數(R2)達到0.884為植被受重金屬污染時開展高光譜遙感監測研究打下了堅實的基礎。
