Part two: Well field development:According to Donghuantuo coal mining and coal storage conditions of the design specifications determined by the mine shaft two levels of development, Deputy shaft extension, skip the main shaft equipment, auxiliary shaft equipment cage. Mine industrial reserves million t, mine recoverable reserves t. Mine length of service for . Part three: Mining coal methods and pick the area tunnel arrangement: This integrated mechanized coal mine in light of specific conditions of the mine to determine the length of the face: a mechanized coal face for the length of 215 m, Jin, 5 knives, 1 layout production mining area, the mine used to long Wall retreat mining law, all managed by falling roof. Part four: Mine Ventilation: According to the mine open up mining conditions, mine ventilation identify ways for the central border ventilation, air volume allocation from the field, face the use of Uventilation, heading face with local fan out of ventilation, according to the ventilation easy, the difficult period The greatest resistance option 2 KZD № 24major fan, with the main mine fan antiair wind tunnel, the main fan motor and a reasonable selection, ventilation costs are lower. Part five: Mine safety technology measure: Donghuantuo coal partially has the gas to gush out the abnormal phenomenon, and once is saved the coal security supervision bureau to list as the A level hidden danger, seriously affects the mine Special part:donghuantuo,Its main content includes:Donghuantuo coal mines coal beds, partially has the gas to gush out the abnormal phenomenon, and once is saved the coal security supervision bureau to list as the A level hidden danger, seriously affects the mine pit the safety in production. For practically strengthens the mine pit safety in production management dynamics, achieves guards against in advance, enhances the mine pit to guard against resists natural calamities the ability, it is necessary to gush out the situation to the coal bed gas to carry on the monitor, and the union daily gas inspection data carries on the science reasonable analysis, finds out Donghuantuo the gas to gush out the rule, and formulates set of science, the reliable gas preventing and controlling technology, raises the damp preventing and controlling technical level, guarantees the mine pit safety in production. Translated part:The Features and Prevention of the Gas Pouring from the Breaking Coalbed of the Comprehensively Mechanized Mining Face Keywords: ventilation 。safety 中國礦業(yè)大學 2020 屆本科生畢業(yè)設計 第 9 頁 目 錄 1 礦區(qū)概況及井田地質特征 ..............................................................................................................12 .............................................................................................................................12 ..................................................................................................................12 .........................................................................................................................12 ..................................................................................................................12 ...........................................................................................................12 ...........................................................................................................12 ..................................................................................................................12 ......................................................................................................................12 .................................................................................................12 ...........................................................................................................13 .............................................................
