绪言我国大量地蕴藏着适于采用倾斜分层下行陷落采煤法开采的缓倾斜厚煤层,但适合于各矿区特定地质条件的巷道布置开采顺序等重大技术问题还未获得解决,其主要原因之一是影响该采煤方法的重要因素——巷道维护问题至今还没有进行过研究。随着我国社会主义建设的发展,国民经济对煤矿工业日益增长的要求,需要我们进一步改善倾斜分层下行陷落采煤法的巷道维护,以及解决目前所存在的巷道布置等重要问题。本文是根据在开滦林西煤矿厚煤层采区中所观测的资料,试图对有关倾斜分层下行陷落采煤法中的巷道维护问题,特别是采准巷道与回采工作面的位置关系对其维护的影响加以探讨,以便作为选择合理的巷道布置开采顺序等的重要依据之一。
INTRODUCTION In our country, a large number of gently-inclined thick coal seams suitable for mining with inclined stratified descending coal mining are available, but the major technical problems such as the order of mine layout suitable for the specific geological conditions in various mining areas have not yet been solved First, an important factor that affects the coal mining method - No research has been done on roadway maintenance. With the development of socialist construction in our country and the ever-increasing requirements of the national economy for the coal mining industry, we need to further improve the roadway maintenance for the inclined mining method with the downward stratified downward settlement and solve the important problems such as the existing roadway layout. Based on the data observed in the thick seam mining area of Linxi Coal Mine in Kailuan, this paper attempts to analyze the problem of roadway maintenance in the inclined subsidence downward falling coal mining method, especially the relationship between the location of mining roadway and mining face The impact of maintenance to be explored as one of the important bases for selecting the order of mining, etc., for choosing a reasonable roadway.
