Based criteria by which the results of the computer simulation, the optimum strength of reinforced soil-array. It is shown that this technology can be used to strengthen in the sinking of underground mine workings in the loose soil.</p>constructionminingsoilstabilityreinforcementmodelingстроительствогорные выработкигрунтыустойчивостьукреплениемоделирование[Croce P., Flora A.
