zh.zkazgan copper deposit is strongly exploited since 1942. Its typical feature is multilevel mineralization. mine′s thickness of sedimentary rock. Primary copper supply is from 150 to 450meters in depth. Capacity of ore body is 1,5～30 m; suddenly 30 - 60 meters. High capacity parts of deposit is mined oUt by room -pillar system. Stress state of rock mass of the deposit is characterized by that, what horizontal stresses is higher in 4～ 10 times than vertical stresses, which is caused by weight of straining thickness of sedimentary rock and submeridianally oriented. At present over than 50 thousands of pillars is formed as the result of deposit mining. mined oUt area is divided on separate parts by over than 400 barrier and chain pillars. Spread of primary traderground tunnels exceeds 1200 kilometers, 540kilometers of the spread is operating mines. Tens of any purposes shafts are exploited with general spread of 45 kilometers. Some its decreasing at last time is caused by filling of emptiness by loosened rock as the result of happening falls at mines (Fig. 1).

食管癌(esophageal cancer)是全球第九大常见恶性肿瘤,目前早期食管癌的诊断率还很低,患者确诊时多已失去手术机会,而晚期食管癌患者由于吞咽梗阻而不能正常进食,全身情况极差,有时根本不能耐受常规放、化疗,因而食管癌的内镜下治疗显得更重要.近年来,随着内镜技术的迅速发展,许多早期或中晚期食管癌的患者均可通过镜下治疗获得满意的效果.

Journal of Central South University 2015年第4期22卷 1276-1286页

A field study was conducted to determine the behavior and distribution of arsenic during the pyrometallurgy process in a typical SKS(Shuikoushan) lead smelter in Hunan province, China. Environmental influences of arsenic in selected samples were evaluated. Arsenic contents in all input and output samples vary from 0.11% in raw lead to 6.66% in collected dust-2. more arsenic is volatilized in blast furnace and fuming furnace(73.02% of arsenic input) than bottom blowing furnace(10.29% of arsenic input).There are 78.97%, 13.69%, 7.31% of total arsenic distributed in intermediate materials, stockpiled materials and unorganized emissions, respectively. matte slag-2, collected dust-1 and secondary zinc oxide are hazardous based on the arsenic concentrations of toxicity characteristic leaching procedure. According to risk assessment code(RAC) guideline, arsenic in collected dust-1 poses a very serious risk to the surrounding environment, arsenic in speiss, matte slag-2, water-quenched slag and secondary zinc oxide show low risk, while arsenic in matte slag-1, collected dust-2 and post dust has no risk to the environment.
