Extension of Excavation Damaged Zone Due to Longwall Working Effect
In advance longwall mining, the safety of mine network, production rate, and consequently, economic conditions of a mine are dependent on the stability conditions of gate roadways. The gate roadway stability is a function of two important factors: 1) characteristics of the excavation damaged zone (EDZ) above the gate roadway and 2) loading effect due to the caving zone (CZ) above the longwall w...

متن کاملEstimation of the Excavation Damaged Zone (EDZ) around TBM Tunnel using Large Deformation Analysis
This paper aims to estimate the distribution and magnitude of the excavation damaged zone (EDZ) caused by the tunnel boring machine (TBM) through dynamic three-dimensional large deformation finite element analysis. Coupled EulerianLagrangian (CEL) analysis was used to consider the large deformation behavior during TBM excavation. The analysis model was verified based on estimations reported in ...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
