MODERN OPPORTUNITIES FOR THE GAS AND GAS DYNAMIC SAFETY INCREASING METHODS DEVELOPMENT AT COAL SEAM MINING BASED ON DATA RECEIVED DURING PREPARATORY OPENING HEADING
Journal Title: Вестник научного центра по безопасности работ в угольной промышленности - Year 2019, Vol 0, Issue 2
Abstract
The initiation of hazardous gas-dynamic phenomena, including sudden outbursts of coal and gas, as well as the likelihood of gas penetration into the working space, are the underground method mining oper-ations rate. Improving coal mining equipment and increasing the depths of mining operations require im-proved methods for predicting gas and gas dynamic hazards. Preparatory workings cause a change in the natural stress state around them. The study of only the gaskinetic reaction of the coal-bearing massif of these changes, depending on the interpretation, can provide an exhaustive and important information, which can be used in conducting the nearby opening (analogue opening) or directly during the extraction pillar mining, the coverage of this task is provided by the presented article. A device is presented for measuring the gas content of a coal seam through boreholes drilled into the face of a preparatory opening.
