开滦钱家营矿煤炭资源现状及开发利用情况分析

在煤层赋存状态不好，地质构造、水文地质条件复杂的情况下，坚持合理配采；坚持科技攻关，减少阶段煤柱，积极推广沿空留巷、沿空送巷新技术；优化工程设计，取消采区隔离煤柱：合理延长工作面走向和倾斜长度，设计高产高效工作面；坚持生产地质勘探，增加矿井经济可采储量；强化资源监督管理，利用经济手段，减少煤炭资源损失是合理开发利用煤炭资源，提高煤炭资源利用率的有效保证。

Report on Analysis of Coal Resources Status and Its Exploitation in Kailuan(Group) Limited Corporation Qianjiaying Branch

In accordance with the bad storage condition, the complicated geological structure and hydro geological condition here, we persist in mining different coal seams in proportions. Moreover, we adhere to tackle key problems in science and technology, reduce bank pillars, actively popularize and apply making use of old tunnels or tunneling along with worked-out sections, optimize engineer designs, withdraw coal-area isolation pillars, reasonably extend the length of seam strike and inclining, devise high yield and high efficiency working face. On the other hand, we also stick to do geological prospecting while mining to increase workable reserves. In short, it is the effective measures for raising the availability of coal resources to strengthen control and management of it, take advantage of economic means to minimize the waste of it.
