实施例3：如图4、5所示，一种硬岩横通道掘进机，包括实施例2所述的钻孔掘进装置，还包括移动台车3，钻孔掘进装置设置在移动台车3上。所述移动台车3上可拆卸设有吊机4。吊机布置在分体钻机1和掘进装置2之间，可为钻孔作业和掘进作业提供必要的吊装工作。
优选地，所述移动台车3的底部对称设有伸缩钢轮301和伸缩行走履带302，伸缩行走履带302倾斜设置在伸缩钢轮301的两侧。即移动平台底部安装有履带和钢轮两套行走装置，两套行走装置均具有伸缩功能，钢轮可在隧道铺设的轨道上行走，履带可直接在洞壁上行走。钢轮行走可实现较长的距离，主要用于在不同工位之间的移动，当移动到指定工作面后，左右履带伸出，左右钢轮收缩，履带行走装置可以承受较大的载荷，防止施工过程中平台的侧翻，也可实现短距离的平台移动和平台姿态调整。
实施例4：一种如实施例3所述的硬岩横通道掘进机的施工方法，步骤如下：
S1：载有分体钻机1和掘进装置2的移动台车3沿主隧洞运动到指定位置；即移动平台可将横通道施工所需的设备运输到指定工位，并在指定工位调整姿态，以满足横通道施工的需求。
S2：当分体钻机处于合适位置后，分体钻机1的液压马达101带动钻头杆104对两个主隧洞之间的洞壁进行钻孔，如图6所示；
S3：当分体钻机1向前钻进一个钻头杆104长度时，松开液压马达与钻头杆104之间的联接，液压马达向后移动空出一根钻杆的距离，然后增加安装一根新的钻杆，新的钻杆与在前 的钻杆插接，液压马达通过新的钻杆和在前的钻杆继续钻孔；
S4：重复在步骤S2～S3直至，钻通两个主隧洞之间的洞壁，如图7所示；
S5：钻孔完成施工后，将移动平台前移，使掘进机到达指定工位，将掘进装置2安装在钻杆上，掘进机的径向伸缩卡钳203-2卡紧钻杆；为提高施工效率可在左右主隧洞内各一台横通道掘进装备；如图8所示
S6：驱动刀盘202旋转，轴向伸缩扭架203-1伸出开始掘进，轴向伸缩扭架203-1伸缩油缸达到最大行程后，刀盘停止旋转，一个掘进行程结束；如图9所示
S7：径向伸缩卡钳203-2松开，轴向伸缩扭架203-1收回，径向伸缩卡钳203-2伸出卡紧钻杆，刀盘旋转，轴向伸缩扭架203-1伸长开始下一个掘进行程；
S8：重复步骤S6～S7直至挖通两个主隧洞之间的洞壁，形成联络通道，如图10所示。
S9：完成掘进工作的掘进装置2，通过逐个拆卸钻杆，将掘进装置2从联络通道内拉出，完成挖掘作业。即掘进装置贯通后，断开两台掘进机之间的钻杆，依靠钻机平台将掘进机拉出横通道，整个工序完成，如图11、12所示。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
