1A case study of multi-seam coal mine entry stability analysis with strength reduction method显示文摘In this paper,the advantage of using numerical models with the strength reduction method(SRM) to evaluate entry stability in complex multiple-seam conditions is demonstrated.A coal mine under variable topography from the Central Appalachian region is used as a case study.At this mine,unexpected roof conditions were encountered during development below previously mined panels.Stress mapping and observation of ground conditions were used to quantify the success of entry support systems in three room-and-pillar panels.Numerical model analyses were initially conducted to estimate the stresses induced by the multiple-seam mining at the locations of the affected entries.The SRM was used to quantify the stability factor of the supported roof of the entries at selected locations.The SRM-calculated stability factors were compared with observations made during the site visits,and the results demonstrate that the SRM adequately identifies the unexpected roof conditions in this complex case.It is concluded that the SRM can be used to effectively evaluate the likely success of roof supports and the stability condition of entries in coal mines.Tulu Ihsan Berk Esterhuizen Gabriel S.

4乳腺癌治疗的新趋势:即刻乳房再造的时代改变了么?显示文摘目的:综述标题中出现“乳房再造”和“放疗”的文章,并对乳房再造中影响决策的因素进行分析,发现即刻乳房重建的新趋势。背景概要:乳癌切除术后放疗新指征的出现使拟行乳房再造患者中的放疗人数有了显著增加。我们分析了这方面的主要研究及其对乳腺癌治疗实践的影响,由于传统即刻乳房再造后放疗的效果不令人满意,新的治疗体系因此应运而生;如果明确需要术后放疗,那么可以考虑延期再造;对于那些术后确定要进行放疗但仍很渴望进行即刻乳房再造的患者,要根据组织特点和血供情况来选择再造;自体组织再造根据组织血管反应性及对放射的耐受性优先顺序为:背阔肌皮瓣、游离腹直肌皮瓣或无对侧组织成分的带蒂横行腹直肌皮瓣、带蒂腹直肌皮瓣或脐周腹直肌皮瓣、穿支皮瓣。结论:当术后放疗指征不明确时,适宜采用术前前哨淋巴结活检,延迟即刻再造或延期再造。Pomahac, Bohdan Recht, Abram May, James W.
