Schcerbiy R. Increase of efficiency of work of roller cone bits on the basis of experimental researches of drilling process

The thesis is devoted to increase of efficiency of deepening of mining holes as a result of experimental researches of influencing of inflexibility and dampfenation of boring instruments on destruction of mountain breed. On the basis of statistical treatment of results of stand researches empiric dependences of mechanical are got boring drilling and energy capacity of process of destruction of mountain breed from descriptions of boring instrument at different values of regime parameters of the boring drilling of mining holes by roller cone bits. The multifactor empirical models of mechanical speed and energy capacity of the boring drilling of mining holes are offered on the basis of results of the planned experiment. The methods of adaptation of results of experimental researches to the industrial terms of deepening of mining holes are developed by roller cone bits.
