Rozpojitelnost hornin při vrtání patří mezi tzv. technologické vlastnosti hornin. Tyto vlastnosti představují projev hornin při jejich uvolňování, rozpojování a opracování různými technologickými způsoby. V období provádění vrtných prací, které mají za cíl vytvoření průzkumného nebo provozního technického díla – vrtu, tyto vlastnosti hornin společně s technickými a technologickými činiteli na vrtu ovlivňují rychlost a kvalitu provádění vrtných prací.
