渡口矿区生产和即将建成投产的矿井有三分之二系采用压入式通风。就山区矿井而言,采用压入式通风具有很大优越性。但自太平矿投产以来,通风上出现了不少问题,主要表现在调风困难,造成远离风机的采区风量不足。这个现象在平顶山矿区一些压入式通风矿井,当采区推向井田边界时也曾发生。因此,弄清这个问题,不仅对今后渡口矿区通风管理新井设计有重大意义,而且对压入式通风使用范围,如何选择山区矿井的
Two-thirds of the mines that are being produced and about to be completed and put into operation at the Dukou Mining Area are constructed with push-in ventilation. In the case of mountain mines, the use of press-in ventilation has great advantages. However, since the Taiping Mine put into operation, there have been many problems in ventilation, which are mainly manifested in the difficulty of adjusting the wind and the lack of air flow in the mining area away from the fan. This phenomenon has been found in some of the press-in ventilation mines in the Pingdingshan mining area and has also occurred when the mining area was pushed to the minefield boundary. Therefore, clarifying this issue is of great significance not only for the design of new wells for ventilation management in the future, but also for the use of pressure ventilation and how to choose the mine of mountainous areas
