The invention relates to a top vertical deep hole construction method for tall chambers, which comprises the following steps of: firstly, dividing the chambers into different categories according to the size requirements of the chambers; then, analyzing the chamber surrounding rock data, and determining the grade of the chamber surrounding rock; and finally, determining the construction steps of the chamber by combining the grade of the surrounding rock of the chamber. According to the method, the chambers are classified, so that a certain construction standard can be formed for chamber buildings with different size requirements, and standardization treatment on the system of the buildings is facilitated; the grade of the surrounding rock of the chamber is determined by analyzing the surrounding rock data of the chamber, the arching height of the chamber can be designed according to the design sizes such as the length size, the width size, the height size and the arch height size, then the grade of the surrou
