在大、中型矿井设计中,当遇到井田走向较长,瓦斯含量较大,或主、副井井筒因某些原因不能选择在井田的适中位置时,将存在着一般通风方式(指中央并列、中央边界或对角式)和分区通风方式的选择问题.一般说来,条件合适时采用分区通风方式,矿井的技术经济指标较好.试从我院设计的河南安阳龙山斜井及河北峰峰万年矿的情况分析如下.
In the design of large and medium-sized mines, there will be a general mode of ventilation (ie central parallelism) in the case of encountering a long well field, large gas content, or the main and auxiliary well shafts can not be selected in a suitable position in the minefield for some reason , The central boundary or diagonal) and the choice of district ventilation.Generally speaking, the district ventilation mode is adopted when the conditions are suitable, and the technical and economic indexes of the mine are better.From the design of Longshan Inclined Well and Hebei Peak in Anyang, Henan Province Feng Wan mine situation is as follows.
