矿图读取、井下生产系统及采煤方法探讨
|
摘要
探讨矿图读取、井下生产系统及采煤方法。矿图的读取需要遵循一定的原则,即看清图名,弄准比例,找出北方向。应了解井田的产状与构造,识别开拓巷道、准备巷道、回采巷道,了解生产系统,推断整个生产系统运行经过的具体路径。要掌握井下生产系统,包括了解矿井工作制度、设计生产能力和服务年限。掌握矿井开拓系统。结合煤层赋存条件、煤层倾角、煤厚、煤层构造等地质条件,明确各采煤工艺优缺点及适用条件。掌握采煤工作面情况,通过单层布置或联合布置的方式,进行回采巷道布置。
The mining map reading,underground production system and mining method are discussed. The reading of mining map needs to follow certain principles and methods,that is,to see clearly the name of the map,to determine the proportion,to find out the north direction. It needs to understand the occurrence and structure of the mine field; to identify and develop roadways,prepare roadways,mining roadways,to infer the specific path through which the entire production system operates. Underground production system should be mastered,including mine working system,design capacity and service life. Combining with geological conditions such as coal seam occurrence condition,coal seam dip angle,coal thickness and coal seam structure,the advantages,disadvantages and applicable conditions of each mining technology are defined. It needs to master the situation of coal mining face,and the layout of mining roadway is carried out through single-layer layout or joint layout.
