Research to establish the equation of the principle of claystone breaking under the seabed

Abstract

The rule of breaking rock has practical significance in the process of
controlling the blasting for the optimization of mine production or
construction of blasting works. The equations describing the particle size
distribution after the explosion are established in an experimental form
corresponding to the specific conditions of the blasting work. It only has
the meaning of a mathematical regression function and does not reflect
the characteristics of the rock type, explosive conditions and explosive
results. This research has exploited the theory of rock breaking from the
point of view of probabilistic energy to establish the equation of rock
breaking of claystone in water. This is a form ofsemi-empirical equation,
which contains 4 empirical coefficients reflecting rock characteristics,
explosive conditions, explosive energy absorption characteristics of rocks
and actual destruction volume, determined for each type of rock. Through
conducting experiments, processing experimental data and solving a
system of four equations, four coefficients of the equations that
characterize the breaking properties of claystone under the seabed have
been found. The error of the average particle size between the actual and
calculated valuesfrom the equationsislessthan 7% to 10%. Ttis possible
to confirm the accuracy of the semi-empirical equation describing the
particle size distribution rule when the claystone is exploded underwater
