Mine curve determination method and system

Abstract

The invention discloses a mine curve determination method and a system. Based on the method provided by the invention, by means of a computer platform, the program is rapid and accurate in calculationand easy to operate, the problems that when a Q-S curve is applied in the past, calculation is tedious and slow, the calculation workload is large, and errors are prone to occurring are solved, and therefore the working efficiency and precision are greatly improved, and the requirements for coal mine safety production and design and mine water prevention and control work are continuously met.

Description

technical field [0001] The present application relates to the field of software technology, in particular to a method and system for determining a mine curve. Background technique [0002] The water-richness of the coal mine aquifer is expressed by the unit water inflow q of the borehole, and the limit value of the unit water inflow q is obtained according to the actual statistical data. Usually, the water-richness of the aquifer is divided into four levels according to the unit water inflow (q) of the borehole (see Table 1 for details). [0003] Table 1 Grade standard of water richness of aquifer [0004] grade standard water-rich q value [L / (s m)] 1 Weak water richness q≤0.1 2 Medium water richness 0.1＜q≤1.0 3 Strong water-rich 1.0＜q≤5.0 4 Extremely water-rich q＞5.0 [0005] Table 1 [0006] In the practice of coal mine production, the relationship curve between the flow Q of the well and the water level drawdown s is often d...
