Increase in rock drill penetration depth
Autor: S. E. Alekseev, B. Kubanychbek
Publikováno v: Interexpo GEO-Siberia. 2:95-100
The application range of remote drilling machines is described. The common shortage of these machines is the dependence of the blow energy transfer to the bottomhole on the bottomhole depth. Aimed to reduce the influence of this factor, it is propose

Small-size downhole air drill hammers of increased capacity
Autor: V. V. Timonin, S. E. Alekseev, D. I. Kokoulin, A. I. Popelyukh, A. A. Repin
Publikováno v: Journal of Mining Science. 52:1122-1128
The authors review key approaches to designing small-size air drill hammers. The approach to increasing impact capacity of air drill hammers by means of buildup of blow frequency is substantiated. The experimentally obtained and compared characterist

Substantiation of type and parameters of downhole air hammer with a view to increase small diameter hole drilling velocity
Autor: S. E. Alekseev, B Kubanychbek, I. O. Shakhtorin, D. I. Kokoulin, V. I. Klishin
Publikováno v: Journal of Mining Science. 51:1126-1131
The article substantiates the need of designing a rotary–percussion drilling tool to drill holes 40–60 mm in diameter and to 50 m long. The drilling rig with a downhole air hammer has been designed and manufactured. The authors have carried out a

Downhole high-pressure air hammers for open pit mining
Autor: V. N. Karpov, S. E. Alekseev, V. V. Timonin, A. A. Repin, B. N. Smolyanitsky, A. I. Popelyukh
Publikováno v: Journal of Mining Science. 50:929-937
The energy upside potential of downhole air hammers is considered. The article presents the constructional diagram of a new air hammer using high compressed air pressure (up to 3 MPa). The experimental testing of the operating cycle of the air hammer
