浅埋煤层矿山压力特点与支护技术

Characteristics of Underground Pressure in Shallow Seam and Its Supporting Technology

矿山压力是由于工作面岩层被开采,导致上覆岩层破断引起。了解矿山压力的特点与规律,可以更好地选择工作面支架的支撑力,提高工作面回采速率,提高煤矿产量,增加企业收入,对于煤矿开采有重要的意义。

The mine pressure is caused by the overlying strata breaking due to the working face strata are mined.Knowing the characteristics and rules of mine pressure can help to choose the support force of working face support better,improve the mining rate of working face,increase the output of coal mine and increase the income of enterprise,which is of great significance for coal mining.
