Abstract
The know-how of layer improvement of thick hollow seams in the mines of Kuzbass is analyzed. The conclusion is made about the necessity of subcladding justification of the location of local development workings of layer 2, providing the minimization of costs for their development and maintenance. The influence of mining engineering factors on the stress-strain state of rock massif in the vicinity of layer 2 layer workings has been investigated. Recommendations on the choice of rational location of local development workings are made. The economic benefit from the implementation of the developed recommendations is estimated.
