| 摘 要： | 2002年10月26日,三河尖煤矿21102工作面发生了底板突水灾害,分析认为突水水源为奥陶系灰岩水,导水通道为隐伏的断裂构造。为尽快恢复生产,实施了工作面两道构筑高压水闸墙的治理方案,将高压奥灰水封堵在工作面老空区内。围绕水闸墙施工出现的技术难题,采取了: a. 围岩加固防渗; b. 安装导水筒降温; c. 优化材料配比,降低水化热,提高混凝土强度; d. 自制混凝土料的搅拌、输送设备,确保大体积混凝土体的连续浇灌等技术措施。该项工程已经历了1a多的检验,堵水效果十分显著。

| Abstract: | On October 26, 2002, a floor water burst emerge d in 21102 working face of Sanhejian Coal Mine. The source of water burst is Ordovician Karst water, th e channel is hidden fault structure. In order to seal Ordovician Karst water in mine goaf, two lock walls located in roadways were built. There are some technic al problems in the project. So following measures were taken: a. strengthening s urrounding rock to prevent leakage; b. installing water pipe to low water temper ature; c. optimizing concrete material, lowering water chemical heat, increasing concrete strength; d. self-making equipment for stirring and transport concrete to ensure continuous grouting. This project has been tested for more than one y ear, the result is excellent. |
