摘要
本文所探讨井巷断面优化的前提——矿井总负压的确定,改变了前人以不超过3000Pa风压为原则的观点。考虑井型、开拓方式、井深、通风方式、沼气含量、煤层倾角等主要因素,使所预测的总负压落在合理的取值范围内。它不仅完善了矿井的优化理论,也为如何预定矿井总负压开辟一条新的技术途径。
Determination of the gross negtive pressure for a colliery.that is the prereguiste is discussed in this paper for the optimization of drift cross-secfions.which has improved the viewpoint of more than 3000 papressure as the limitation. Considerating of the main factors such as the mine capacity .development method .mechane content .inclination of the seums,and so no .let the gross negtive pressure be forcast into the reasonable range.Not only has the study improved the optimu theory of mine designs but also opened a new way to forecasting the mine gross negtive pressure.
