Problems of Coal and Gas Outburst Identification and Regional Prediction in Guizhou Province
摘要
Abstract
The status quo of coal and gas outburst identification and regional prediction in Guizhou Province was investigated. Aiming at the problems of the differentiation of outburst appraisal scope, this paper discusses the working specifications of detection and inspection institutions, the preparation of mine appraisal engineering quantity and long-term mining planning, and proposes the necessity of formulating detailed rules (or guidelines) for the implementation of Guizhou coal and gas outburst appraisal; under the condition that the main body of the regional forecast implementation is not clear, the necessary conditions for the mine to organize the implementation of the regional forecast by itself are proposed, and the minimum reasonable range of the regional forecast is analyzed. This paper defines whether to carry out regional prediction or outburst identification for regions that are inclined to exceed the original identification level by 50 m and regions that are beyond the original identification level by 50 m or beyond the original identification level; it is necessary to define the coal seam for testing gas parameters and related gas parameters in the mine; for the problem that the supervision department is more strict in the index critical value management, it is more reasonable to return to the requirements of the rules and regulations.关键词
