Method of degassifying a massive of rock

Abstract

This invention concerns the mining industry, chiefly the coal industry, and can be used for the degasification of coal layers and interfering rock. The method of preliminary extraction of gas with underground development of burning minerals, including the pumping of gas through a collector, carried in the plane of the degasifying layer, discharged from rock pressure by means of extracting the lower lying layer, is known. However, the given method does not make it possible to degasify the interfering rock. Another method, consisting of the fact that from the mining development in the lateral rock, chambers are made, from which a group of wells are bored, and the latter are united with the gas removing system, is well known. This method has the inadequacy that the well of each chamber is connected to the gas removing system of the pipelines, and this leads to an increase in the price of the method. A new system is presented for the degasification of the massive of rock which is presented in an illustration...... The advantage of the suggested method consists of the fact that material outlays are reduced for the unification of each chamber with the gas removing pipeline, and besides this,  More>>
