Stability of workface using long-wall mining method in extremely thin and gently inclined iron mine

Long-wall mining method has its own advantages, such as small mining-cutting ratio, the simple technique of recovery and high level of mechanization, which is the optimal method used to mine gently inclined and extremely thin iron mine. How to ensure the safety of workers and equipment during mining is the key technical process. Based on elastic-plastic mechanics theory, the mechanic model of long-wall method mining gently inclined and extremely thin iron mine is established and the critical safety distance of workface is obtained. With the FLAC-2D simulation software, the rule of stress change, the deformation of workface and surrounding rock in different control-roof width are also summarized. The final results accord with the ones of theory test. We confirm the support-frame resistance of workface by analogy-statistic method. The results prove that hydraulic support-frame have the ability to provide enough pressure to assure the stability of working face within the 5-m of control-roof width.     

浅谈钢铁工业的清洁生产与可持续发展

清洁生产和可持续发展概念高度一致,两者相辅相成促进社会协调健康发展。钢铁工业对资源和能源消耗量大,社会可持续发展要求钢铁工业实施清洁生产。钢铁工业实施清洁生产要从节约资源和能源、改进工艺和设备、加强管理、必要的末端治理等方面进行。清洁生产是钢铁工业可持续发展的必然选择。     

附着态TiO2光催化降解壬基酚的研究

采用sol-gel法制备TiO2薄膜,以该薄膜为催化剂,研究了在H2O2存在的条件下,对内分泌干扰物质壬基酚的光催化降解反应。分别研究了pH值、H2O2的加入量,壬基酚的初始浓度以及光照时间对降解反应的影响。结果表明：在pH=5,30mg／L的H2O2中对初始质量浓度为20mg／L壬基酚的溶液光照180min有较好的降解效果。
