安徽省两淮煤田是我国煤炭重点建设地区,但在新井建设中,井筒穿过的表土深,流砂层厚,地压大,合理的井壁结构和设计计算方法是一个急待解决的问题。我院在安徽煤炭公司及有关单位的支持与配合下,自一九八○年起开展了《井壁结构》的科学研究工作。它的目的是:通过井壁结构试验和理论分析,研究各种井壁结构的内力和强度及其与应变关系等,为解决深井冻结和钻井合理的井壁结构及设计计算方法提供依据。 Anhui Lianghuai Coalfield is a key construction area for coal in our country. However, in the construction of new wells, the deep well with topsoil passing through the wellbore, thick sand flow, large pressure and reasonable wall structure and design calculation method are urgent problems to be solved. With the support and cooperation of Anhui Coal Company and relevant units, our institute has conducted scientific research work of “Shaft Wall Structure” since 1980. Its purpose is to study the internal force and strength of various borehole structures and their relationship with strain through borehole structure test and theoretical analysis and so on, so as to provide basis for solving borehole structure and design calculation method of deep well freezing and drilling well.
