Longwall Top Coal Caving Method for Barapukuria Coal Field, Dinajpur, Bangladesh[ ]


The present research work deals with the coal extraction method for the Barapukuria Coal Field, Bangladesh. Various LTCC parameters, for example top coal failure behavior, strata caving mechanism, vertical stresses and abutment stresses, were evaluated for this mine using Examine2Dsoftware for the assessment of LTCC technology. The stress response of natural caving roof were studied, by using numerical simulation of LTCC mine excavation of Stage II and III associated with magnitudes and distribution contours of vertical stress (s1), strength factor, subsidence, area of deformation and displacement of surrounding rock strata of a stage III excavation mine panel, fracturing and caving of top coal and overburden strata. The magnitudes and distribution contours of vertical stress (s1) imply that the vertical stress is more obvious in the area just above the excavation panel ranging from 1.5 to 2 m at the bottom and roof of the panel. Above the easily cavable zone of 1.5m, there lies another zone of 2 to 2.5m, between stage II and III excavation panel, where strength factor is 1.06, which could be induced to cave with the help of hydrofracturing. According to the results, by considering all factors it was found that Longwall Top Coal Caving (LTCC) method would be a preferred and alternative method for mining in seam VI’s stage III of Barapukuria Coal Mine. It will increase recovery ratesup to 75%, which will contribute additional support to further new power plants.

A Class of SEC-DED-DAEC Codes Derived From OLS Codes and Decoded With Low Latency[ ]


Radiation-induced soft errors are a major reliability concern for memories. To ensure that memory contents are not corrupted, single error correction double error detection (SEC-DED) codes are commonly used, however, in advanced technology nodes, soft errors frequently affect more than one memory bit. Since SEC-DED codes cannot correct multiple errors, they are often combined with interleaving. Interleaving, however, impacts memory design and performance and cannot always be used in small memories. This limitation has spurred interest in codes that can correct adjacent bit errors. In particular, several SEC-DED double adjacent error correction (SEC-DED-DAEC) codes have recently been proposed. Implementing DAEC has a cost as it impacts the decoder complexity and delay. Another issue is that most of the new SEC-DED-DAEC codes miscorrect some double nonadjacent bit errors. In this brief, a new class of SEC-DED-DAEC codes is derived from orthogonal latin squares codes. The new codes significantly reduce the decoding complexity and delay. In addition, the codes do not miscorrect any double nonadjacent bit errors. The main disadvantage of the new codes is that they require a larger number of parity check bits. Therefore, they can be useful when decoding delay or complexity is critical or when miscorrection of double nonadjacent bit errors is not acceptable. The proposed codes have been implemented in Hardware Description Language and compared with some of the existing SEC-DED-DAEC codes. The results confirm the reduction in decoder delay.
