前言自从水力采煤在我国开滦林西矿和萍乡矿试验成功以后,经过一年多来生产实践的证明这一世界上最先进的采煤方法确实具有许多巨大的优点,非常符合我国多、快、好、省的建设方针,但根据目前资料来看水力采煤所达到的回收率还是比较低的,因此有些人对在我国大力开展水力采煤抱着怀疑和犹豫的态度,因此研究水力采煤的煤炭损失并进一步提高其回收率对我国大规模的推广水力采煤具有很大的意义。
Preface Since the hydraulic coal mining in our Kailuan Linxi mine and Pingxiang mine after the successful test, after more than a year of production practice proved that the world’s most advanced coal mining method does have many great advantages, in line with our country, However, according to the current data, the recovery rate achieved by hydraulic coal mining is still relatively low. Therefore, some people are skeptical and hesitant about vigorously carrying out hydraulic coal mining in our country. Therefore, Coal mining losses and further increase their recovery rate for our large-scale promotion of hydraulic coal mining is of great significance.
