摘要
随着煤炭形势的持续升温,平煤天安四矿主井原设计提升能力已不能满足要求,为了进一步提高提升能力,需要对现有部分提升设备进行改造,改造后提升能力可达145万t/a,并且确保提升系统的安全可靠性,满足《煤矿安全规程》的要求。
With the development of the coal production in our country, the lifting ability of the main mine is unable to meet the requirement. To enhance the lifting competence, it is necessary to improve some of the existing lifting apparatuses. After improvement, the lifting competence is expected to reach 1.45 million tons per year. And the new device can ensure the safety and reliability of the lifting system and meet the requirements of the Safety Regulations of Coal Mine.
