0 前言立井钢性井筒装备通常采用 4ｍ罐梁层间距结构形式。随着井筒深度增大 ,井筒装备钢材消耗和井筒通风阻力随之增大 ,加大罐梁层间距可有效地减少井筒装备钢材消耗量 ,降低通风阻力。经过计算 ,将罐梁层间距由 4ｍ增大到 6ｍ ,可节省井筒装备钢材将近 1/ 3,降低通风阻力 3
0 Foreword Wells shaft steel shaft equipment commonly used 4m tank beam spacing structure. With the increase of wellbore depth, the steel consumption of wellbore equipment and the ventilation resistance of wellbore will increase. Increasing the space between canister girders can effectively reduce the consumption of steel in wellbore equipment and reduce the ventilation resistance. After calculation, the canister layer spacing increased from 4m to 6m, can save nearly 1/3 of wellbore equipment steel, reduce the ventilation resistance 3
