What safety factors should be considered when using hydraulic anchor rod drilling vehicles for coal mines in thin coal seam mining（haoyun）

The editor of Shandong Haoyun Heavy Industry Machinery Co., Ltd. will discuss the safety factors that need to be considered when using hydraulic anchor rod drilling vehicles for coal mines in thin coal seam mining.

The use of hydraulic anchor rod drilling vehicles for coal mines in thin coal seam mining requires consideration of the following safety factors:

1、 Gas and ventilation

1. Gas monitoring and warning: Gas is prone to accumulate during thin coal seam mining. The hydraulic anchor drilling truck used by Haoyun Heavy Industry Coal Mine needs to be equipped with reliable gas monitoring equipment, such as airborne methane power-off meter or portable gas detector, to monitor gas concentration in real time. When the gas concentration reaches the set value, an alarm can be issued in a timely manner and the power will be automatically cut off to ensure construction safety.
2. Ventilation system optimization: Ensure good ventilation in the roadway, arrange ventilation facilities reasonably, ensure that fresh air can be effectively supplied to the operation area of the hydraulic anchor drilling truck used in the coal mine, and prevent gas accumulation and harmful gases from exceeding the standard.

2、 Roof and support

1. Roof stability assessment: Before construction, a detailed geological exploration and stability assessment of the roof rock layer should be conducted to determine reasonable support parameters and anchor rod layout, ensuring that the anchor rods can effectively anchor the roof and prevent roof accidents from occurring.
2. Support quality control: Strictly follow the design requirements for anchor rod installation, ensuring that the length, diameter, spacing, anchoring force and other parameters of the anchor rod comply with regulations to ensure the quality of support.
3. Temporary support measures: Before the anchor drilling operation, temporary support must be carried out, such as using single pillars, metal roof beams, etc., to prevent the roof from falling off during the drilling process.

3、 Equipment and Operation

1. Equipment selection and maintenance: Choose a hydraulic anchor drilling rig suitable for thin coal seam mining conditions, whose structural dimensions, working parameters, etc. should meet the requirements of roadway space and construction. Regularly maintain and upkeep equipment to ensure good performance and prevent equipment from running with problems.
2. Operator training: Operators must undergo professional training, familiarize themselves with the structure, performance, operation methods, and safety precautions of hydraulic anchor rod drilling vehicles used in coal mines, and pass the assessment before they can start working.
3. Development of safety operating procedures: Haoyun Heavy Industry shall develop detailed safety operating procedures, specifying the operating steps and safety requirements for each link of equipment start-up, operation, stop, etc. Operators must strictly follow the operating procedures.

4、 Other safety measures

1. Fire prevention and extinguishing measures: in thin coal seam mining, the risk of coal spontaneous combustion is high, so effective fire prevention and extinguishing measures should be taken, such as spraying fire retardant, setting firewall, strengthening ventilation management, etc., to prevent fire accidents.
2. Dust control: A large amount of dust will be produced during drilling, which will cause harm to human health and the environment. Measures such as spray dust reduction, ventilation and dust removal should be taken to reduce the dust concentration.
3. Safety inspection and hidden danger investigation: Establish a sound safety inspection system, regularly conduct safety inspections on hydraulic anchor rod drilling vehicles and operating environments used in coal mines, and promptly discover and eliminate safety hazards.
